Below left is a tomboyish outfit in burgundy/blue/gray [details here]. Below right is a girlier version using some of the same pieces in the same general color scheme. The two outfits are different enough but still stays true to my style.
sunglasses: Walmart aviator (similar)
sweater: H&M (may still be in stores)
bag: Marc Jacobs large Single - gift from aunt (sold here)
