Our uniforms work as hard as students do

Whatever kids have to dish out, a DENNIS uniform can take it. From math tests to soccer practice, shouldn’t your students wear the best, from head to toe?


Classic products, fresh perspective

At DENNIS we don’t devote ourselves to trends, but we are committed to designing our uniforms the right way from the start and revising them to suit the changing needs of students. We pay attention to every detail, constantly evaluating and — when necessary — updating fit, tailoring, fabric, color and more until we’re right on target.



Plaids that stand the test of time

Our signature DENNIS plaid garments are built to last, starting with specially-woven fabrics custom-dyed to guarantee color consistency. Every detail counts — plaids match at the seams, and growth features in waistbands and hems help garments grow with your kids. Finally, pleats are baked in to stay crisp, wash after wash. Your uniforms will look as good on the last day of school as on the first!

DENNIS polos for the win!

Jersey, Piqué or Performance? Short or long sleeve? A cute cut just for girls? We’ve got it. With sturdy construction in a substantial ring-spun cotton/poly blend, our polos are soft, durable and thoroughly wearable. Join the legions of DENNIS polo fans — get yours today!



Meet your new favorite pants

Our flat-front Irvington & pleated Hawthorne pants & shorts are designed to outlast kids — from busy Kindergarteners to hardworking high-schoolers.


With durable construction, adjustable waistbands for younger kids and a generous size range to fit everyone, our pants & shorts are an instant classic.



Not your ordinary polo shirt

New to our line! It’s the best of both worlds: the cooling effects of a wicking fabric, in a finish that fits right in with the rest of the class.


Our 100% polyester performance fabric wicks moisture away and keeps you cool, but has a soft hand like our classic uniform polos.
