Halter dresses are popping up everywhere in Hollywood. These dresses are perfect for the hot summer weather. You get to show off a sexy back and toned shoulder and best of all you don't have to wear a bra.

Especially popular this summer is the long flowy dress style. It is loose and comfortable, perfect if you are pregnant and fun to wear over your bathing suit at the beach like Dayanara.

Jessica and Vanessa have chosen more feminine and sexy styles. They are fitted and show off great cleavage.
