Uniform Orders

Uniform Ordering

York Catholic Middle & High School is transitioning uniform companies from Flynn O’Hara to Dennis Uniforms.  For the 2023-24 school year, families will have the option to continue to use the Flynn’s they have or purchase new Dennis uniforms.  Flynn’s will no longer be available for purchase. The old crest logo on uniforms will not be permitted after the 2023-24 school year, but Flynns with the newer YC-letters logo will be permitted. Click the button below for more information from Dennis Uniforms.

Please do not be concerned about the Pre-Order notification that appears on the Dennis website.  It is a generic notification that will disappear soon. Dennis Uniforms is working hard to fulfill your entire school uniform order by August 25. Their priority is to make sure each student has a uniform to start the school year. This means they are fulfilling partial orders as they work to create more inventory.
