Sometimes summer days can get chilly, but you can still feel and look cool and fashionable with the proper outerwear. Stick your black blazer in your closet and try a white blazer. It feminizes and adds a chic structure to your outfit and goes with everything. A light open-faced sweater with short-sleeves is also great to throw on over a lacy cami or a strapless dress on a chillier night. And lastly, a deep V-neck buttoned cardigan looks great casually or dressy. Put it on over a white tank top of a sexy strapless dress.
