Classy girls know how to show skin without over doing it. Take this Angelina Jolie look for example, she is wearing a one shoulder dress that is showing skin in the right places without compromising on class. A great style tip would be balancing how nude you go with the design of a garment. Has it got a short hem? Balance this with a high neck. Are you showing your shoulders? Keep the structure of the dress classy. Always focus on only one area of your body to expose keeping the look desirable but elegant.
