I love adding contrast into my wardrobe.  My general go-to is to wear something casual with something dressy, but I also like adding dark and light pieces together to create that perfect balance.  Once upon a time, I wouldn't dare wear ANYTHING that showed my bra, but now, your bra is almost part of your outfit thus just as important.  I love adding a pop of black under this lace tee.  Just a little something interesting without showing too much.  Add some high waisted shorts or pants under so you only show a tiny bit of skin.  This a great thing to try in the summer months when it's hot and you are dying to wear as little clothing as possible!
