Most of my clothes are from Mod Cloth, which is an online store. It's all vintage inspired or actual vintage clothing from various time periods. It's really great and I get compliments on my Mod Cloth clothing all the time.
I also have quite a few solid colored t-shirts, raglans, and tank tops from American Eagle and VS PINK.
I spend a lot of my free time in the yoga studio, so I have tons of Lululemon yoga pants, shorts, tank tops, and sweatshirts, but I only ever wear them at the studio.
