Do you associate Theory with suits and paired-down pieces? Their Summer 2010 pieces will completely change your mind. Yes, the simplicity factor is still present, but it's spruced up for warm weather fun. Here are three looks that will make any girl instantly cooler. What I especially love is how the looks are paired with totally unexpected footwear, like the one-shouldered dress with oxfords instead of sandals. There are way more flirty frocks, rockin' denim, and rompers where that came from. Click through to experience Theory's amazingly styled Summer look book.
