Reviews from Our Custom Partners and Retailers 

"Party Shirt International has brought the fun and flair to our customers! The Party Shirt has been our top selling tech shirt since we brought them into the shop. We love witnessing the joy these shirts bring to everyone who visits us!"

Ever since we started carrying Party Shirts all of our dreams have been coming true. The product is playful, quality and resonates with a huge segment of customers. The designs are authentic and fill a niche that no other line is hitting although lots have been trying. They ship fast and accurately and we are happy to have them as a vendor in our shop.

"domestic and international GRVL events from Finland to Colorado and they’ve delivered every time"..... There’s no limit to originality you can conjure up with this crew, which has allowed us to explore our creative side as a brand. Thanks to Party Shirt International we’ve been able to provide our participants with the physical manifestation of fun that we work so hard to incorporate into all of our events.
