Toga Party: Rihanna and Stephanie Pratt Wear One-Shoulder Dresses

We all know that hips, butts, and arms can be problem areas when it comes to getting dressed – but does anyone ever worry about their shoulders?

One-shoulder dresses are a sexy way for anyone to show a little skin, as these stars show.

Stephanie Pratt breezed out to dinner with friends in this floral one-shoulder drape, with a unique single long sleeve.

The Hills star’s bohemian look was complete with a long lavaliere, and leather clogs.

Rihanna left the Record Plant in LA in a shimmery black dress with one puffed sleeve (left). Belting the dress saved it from looking a little like a trash bag. One-shoulder dresses even make great vacation cover-ups, as Catherine Zeta Jones shows while holidaying in Majorca (right). The frock is an elegant alternative to the poolside sari.

Just make sure to wear sunscreen when you try one-shoulder dresses, or you could end up with half a tan.
