Free City

Free City is a collection by Ron Herman that is extremely popular right now. They sell comfortable and chic work-out clothing that is comparable to VS's Pink line, though it is priced at a much higher price range.

About Free City:

"FREECITY was founded on the idea that all things are possible. Based in California, FREECITY creates clothing (as well as original structures and one-of-a-kind bicycles) featuring hand-mixed colors and hand-screened graphics, giving each item an individual feeling and fostering the notion that fashion is about personal expression. The resulting aesthetic is a SoCal-cool composite of art, music, design, and free-spirited individualism." - Shopbop

Part of Free City's popularity can be attributed many celebrities wearing it.
