Treasury Dept. is a boutique in Costa Mesa, California that strives to encourage individuality through collaborations with independent designers and unique pieces. The boutique carries clothing from local indie designers that cannot be found within 20 miles. Owners Mitch Moseley and Devin Carlson opened the boutique in 2009 to showcase the styles of their friends who are designers. They hope to keep promoting independent fashion through their own clothing line, an expanded online store, and a new location in the future.
