Tenacity Jeans Mission

Our Mission

Our mission is simple: your clothes should make you feel great. We’re the Tupper sisters and the idea behind Tenacity jeans started because we were tired of shopping for clothes that didn’t fit, let alone flatter, our athletic build.

We believe what you wear says a lot about you. Tenacity jeans are designed with women’s bodies in mind. It’s time to show off, not stuff, our bigger butts and quads into jeans that actually fit. 

These jeans were created for women who refuse to let traditional fashion standards hold them back.

Business Woman Jeans

Bring Out the Best

We want to bring out the best in every woman. 

From designing functional jeans with a feminine pocket to creating and keeping jobs in America, our goal is to make an impact for good in women’s lives.

You have a lot to offer. Our promise is to tenaciously pursue clothing that makes you feel comfortable and confident in everything you do.
