Christian Siriano became famous after winning Season Four of the design competition Project Runway. Now he hosts the reboot of the TV show and has become one of America’s most influential fashion designers.

On top of designing for his celebrity clients, he just launched a limited-edition collection for for J.Jill that is selling out quickly. True to his fashion philosophy, the collection is made for women of every size, age and shape.

The 16 pieces come in Sizes XS-XL. and four size types (Misses, Petite, Womens and Tall). The collection’s tops are available at J.Jill stores including SouthPark and Blakeney. The entire collection — which also includes pants, dresses and a coat — is available online at J.Jill.

“No matter what age you are, where you live or what you do for a living, I want to make you feel good and look great in your clothes,” says Siriano in an interview on the J.Jill website. “What’s appropriate to wear has nothing to do with age. It has to do with lifestyle. I design for someone like my mom who is in her 70s and is living her life and for someone like my sister who is in her late 30s.”
