The most durable uniforms in the industry.

Keeping our focus.

In an industry where brands compete for attention, we stay focused on one thing: delivering top-quality uniforms. Our in-house Product Development team consistently inspects and refines our products to ensure the fit, fabric and color exceed every customer’s expectations.

 

Plaids: a DENNIS tradition.

There’s no better way to display school spirit than with a spirited plaid. Across the country, DENNIS signature plaids are regarded as the best, and we owe it to our best-in-class yarn. Impeccable drape without any stiffness, our famous plaids stay smooth and fresh, wash after wash.

Polos: built to last.

Any enduring structure starts with a solid foundation, sturdy framework and features to protect against the elements. It’s the same with a great polo – construction is key. Our foundation is superior yarn, strong without bulk. The framework is double-needle topstitched seams for strength. And features? Our polos have plenty, from anti-curling collars to side vents for easy movement, and even moisture-wicking innovation in our Performance polo. Long or short sleeve in a classic or feminine fit, DENNIS polos are fade-resistant, anti-pilling and wrinkle-releasing.

 

 

Dress Pants: unbeatable favorites.

From hard-working high schoolers to busy kindergarteners, our bestselling Irvington and Hawthorne dress pants and shorts are designed to keep up with every move. Worn by thousands of students every day, our dress pants and shorts are comfortable, durable and best in class.

Meet the performance tech line: polos, pants, shorts and a skort that are sophisticated enough for the classroom while offering the freedom of motion for a game of dodgeball.
