Love this place. Definitely has a comforting and old school costume store vibe to it but its much more than that! There was a section for birthday items and so much more I want to check out the next time I come. Thank you, team, for making me feel welcome! ❤️

Better to buy early. It’s usually leftovers and quite expensive on halloween eve.

We love Champions and visit often for any costume, balloon, or party needs. They always have a great variety and helpful staff. If you go at Halloween with kids, there are lots of fun and spooky displays. Definitely worth visiting!

Ordered balloons online for my son’s birthday and I definitely recommend it! I got 12 latex balloons, a giant number 4, and a circular foil balloon. All 14 are still flying high almost 6 days later! I put in my order on Friday evening (be sure to put the pickup date and time in the order notes) and it was filled the next morning. I briefly worried they might not last until Sunday evening’s party but I definitely didn’t need to be. They got my order perfectly and it was easy to swing by and pick them up.

They have EVERYTHING and the staff is super nice and helpful!!

Was a little disappointed in the Halloween decorations selection! They had tons of awesome large animatronics as well as a large selection of indoor decorations but definitely lacked in the mid range outdoor friendly decorations. We thought for sure we would be able to get at least lights and some posable skeletons and alas were unsuccessful. All that said they have TONS of options for costumes and other party supplies so if you are looking for a wide selection of indoor party items this is your place!

These guys were great. Helped me get ready at the last minute for my partners birthday. Massive selection of supplies. No need to go anywhere else.

This place is amazing! Not only did they have so many options and great party supplies, but the staff is top notch. Even when I had a specific question for the manager, the entire staff checked on me to make sure I was okay. That is the type a mentality and support I wish I found in every store I go to.

Super helpful staff and huge store for simple party supplies, themed parties and every costume you can think of. Plus random candies, balloons and holiday decor. Got my bachelorette supplies!!

Called in my balloon order and it was ready when they said it would be. Love their decor and costume selection also! Definitely have a bit of everything.

One of the best, if not best costume/party shops on the West Coast. Phenomenal selection and high-quality items. You can find anything you need here from a variety of masks, costumes, paints, party favours, etc. Highly recommended, especially for Halloween or a costume party.

A good supply of costumes, but not a huge selection on party supplies. Slightly pricy. Very friendly and helpful staff.

I absolutely love champion party supply! Ive been shopping here since their old location off Denny and I appreciate everyone that works there as theyre professionals that know everything there is to know about costuming and parties. They do beautiful balloon arrangements, charge a fair price and everybody there is so passionate and polite. I cant say enough good things about Champions.

A legendary, Iconic business, words can not describe. Investigate for yourself, its an experience. 👍🤓

Great store! Best place to go to get party supplies. They got it all! Also best place to buy a costume. Great selection. Get a manufactured costume or make your own. Everything youll need to become a superhero or pirate or princess or whatever.Also cool front window displays!

I needed balloons. Lots of balloons to compensate for the fact that my kid wouldn’t be having a big birthday party for his 10th birthday due to Covid. Champion Party Supply helped me pick awesome balloons that are still floating even after 3 weeks. They also delivered the balloons to the newly established west Seattle island which is currently a major pain to come in and out of. Their customer service is great and the whole store is one of the best I have seen.

Tons of great costuming options.

They have a huge wig selection. We bought a rainbow wig for my daughters Halloween costume. They let us try it on and consulted us on fit. They gave the kids free balloons and have the BEST people working there. I will always go back and support this business.

If you need something for a party, chances are youll find it here. Was happy with the staff, being greeted and offered help when I needed it. Always easy to find what Im looking for here! Store has hand sanitizer when you walk in and has signage stating masks are required, which I very much appreciate!

Champion is costume Oasis with a knowledgeable kind and wonderful staff to match the excellent selection of very specific high quality costumes and endless cornucopia of accessories to match all desires.

Mean customer service and charged me twice for the same wig

Favorite for decorations and party supplies. Always find what I need for a costume.

Locally run party store. Every employee Ive dealt with has been super friendly, and theyve got plenty of options for all your decorating and party needs.

The gentleman I worked with here was so kind and helpful! He let me in before the store opened because I was outside and he was ready early. If he hadnt, I wouldnt have been able to get he birthday supplies I was hoping for (I hadnt done my research on when the store opened). Then he helped me find everything I needed, all with great energy.

Super helpful staff, both on the phone and in-person!

Huge stored with good selection of party customs, favorites, decoratives and ballons!

So glad to see a party store in the area. Great store with lots of stock

I love this place and I cannot believe I havent been in since theyve moved to their new location some three years ago on Elliott avenue. This is the floor plan and space that this company has always needed and they fill it out and utilize it beautifully. Very helpful staff and an incredible breadth and diversity of supplies, decorations, masks, costumes, (for both sale and rental), and much more. When you stop in I suggest you have plenty of time because youll get swept away in the fun and creativity of your reason for visiting.

As most party stores. Very overpriced but lots of stock if you are in a pinch.

When I first moved to Seattle I had ended up in Champion for some stage performance supplies and was thankful to have a resource near by after moving away from my old spots.Later I ended up working there for a few years, apart of the move from the old nostalgic spot and even though it was hard at first I completely came around to loving the new larger space.It’s been a bit since I worked there but I still love it, the people, and am totally impressed by the owner. Small, local and family business, more and more rare in Seattle, a total diamond.Plus what more could you hope for in a party store? You literally can go in and plan the whole thing plus an outfit 😜

Love this place! Ive been coming here for years. The selection is great and the staff is super helpful. Its always great to support a Seattle staple. Thank you Champions!!!

Great customer assistance! Thank you 😊

+s Great Staff, Tons of Costume ideas mix n mash.. Always fun to explore.. 3 stars-s Getting Followed by third party security and watched Constantly while with family.. 2 1/2 Stars..

I love their staff and selection. Theyre helpful when I have questions and back off to let me shop 🙂

Love this place! Overpriced, but they have EVERYTHING you need to put together a gteat costume. Huge selection. Great, helpful employees!!

If you cannot find a costume or a party theme here - it does not exist. Well displayed. Incredible amount of goods. Helpful & courteous clerks. Fun !

This is the very best place to get party supplies or costumes in Seattle. You can find reasonably priced things throughout this store AND, importantly, it is a one stop shop. You can buy cups, plates, utensils, decorations, costume, makeup, balloons and more. Honestly, stop here for any party needs.

Great costume and party supply store, we were looking for costumes for a Mexican themed murder-mystery night. Although they tell us it is crazy good at Halloween time we still found a good array of costumes, accessories and decorations for our needs. The staff were helpful and really friendly

Great staff and a fun atmosphere! Try to go in the morning if you can. A lot less crowded.

Love this store, they have everything! The owner is also super hot. 5 stars.

I was asked by 5 different staff members check to make sure I was finding everything I needed and they were all so kind and helpful. One lady went above and beyond helping me find costume pieces and even gave my son a free balloon when he was being fussy. They have a great selection and fair prices. I will definitely be back for costumes and party supplies!

I needed a pirate costume and I was able to find one there for $20. I was in and out in 10 minutes. The staff was extremely helpful.

This store is AMAZING

The selection was nuts and prices were decent. Easy to get to via the bus as well

I love this place! So many great options for stage wear and home decor

Both of Guys that helped Us out were REALLY HOT!!! Loki has this clean shaven thing working for Him along with a Sexy smile. The Guy behind the register Sexy Cub type.... I would have loved to bring either one or both home

I called before I drove to make sure they had what I was looking for in stock. When I arrived the gentleman had 2 options for me at the front counter. He even helped me look for other items I didnt even know I wanted! Great selection and awesome service. Ill be back.

Great customer service.

Great local source for Halloween and party supplies. They have a new location just south of the magnolia bridge. Lots of parking, so easy in and out. Found everything we needed for my daughters costume.

Always helpful and friendly! This place has everything and more. Stop here for ANY event you are planning. A pizza pinata?? Flamingo string lights? Extra balloons? Yes please!

One stop shop for Halloween. We usually stop by in small groups right before and try the whole ensemble, show it to friends and purchase without much ado. A+ quality

I will come here every time for any and all of my party supply needs! The employees are sooo amazing and helpful!! Love love love them!!

Staff were great. Upbeat and helpful during their most chaotic time of year.

Amazing employees and lots of fun supplies for any party!

I have been shopping for party supplies and costumes at Champions for at least 40 years. At their first location at The pike Place Market, then when they moves to Denny Way, now development has caused them move to Elliot Avenue, I will follow them where ever they go! Great products, great service and just a fun place for products and ideas when getting ready to party!

Got EXACTLY what I was looking for and staff were super helpful, kind, and accommodating. Definitely going back for future events.

This place is amazing! So many costumes and party supplies. Cant wait to go back!

Excellent selection, friendly and helpful staff, and very organized. We did some Halloween shopping on what the manager said was the busiest day of the year, and barely noticed the crowds!

Cass was so incredibly helpful, as well as a lovely human behind the makeup counter! They helped me realize my perfect Halloween vision!

The store had a great selection, and the customer service was fantastic! Downside, was spending $60 on a costume, only to find multiple large holes and snags all along the costume. The wig was in decent shape, but in really disappointed that they would sell this product under the condition its in. With the no refund policy, I cant imagine coming back. Not sure where Ill find such great selection.

They have everything. I mean it... Everything. Costumes, party stuff, holiday stuff... Everything. And very willing to help staff.

A lot of things for your party. And a must go place for your Halloween needs. Friendly and very helpful staffs.

Great local place with an awesome selection of party supplies and costumes.

Erik was awesome, super cool. Really took care of us and helped with numerous suggestions. Day of the Dead never felt so good, is it ok to say that? Rock on!!

The new location is great. Tons more space and new items. And it even has a parking lot!

Most everything you need for a party and wide array of costumes! We’ve been getting costumes here for years. I recently learned they have number Mylar balloons - big win! 4 instead of 5 starts because prices can be higher than online for costumes.

Great cheery place - recd friendly help and found what I wanted!

Everyone is always so friendly and helpful when. I go in :) and its dog friendly

They have so many great balloons! The staff is also very helpful.

Great staff and awesome assortment from costumes to parties.

Fairly large warehouse packed with lots of costumes, party ware, scary Halloween masks and crazy party gags and confetti.

Huge selection. More like a warehouse, has that back stage theatre kind of feel. Super friendly service.

Always a pleasure to explore here.

Gigantic party story in Queen Anne. Great place if you need a great costume, party decorations,. etc.

Great selection of costumes and accessories. Helpful staff.

The perfect place to find anything for a custom party or Halloween

Cool place for Halloween costumes but not really for lights or decorations.
