Dresses like this Long Sleeve number with cut-out sides, are among the new trends for Fall 2010. Celebs like Lady Gaga and Rihanna were the first to rock this "Cut-Away" look. The Dress above, by Blaque Label, is sexy yet sophisticated; subtly exposing the waistline while still retaining an element of class.

It is available at Fashion Lounge for $68.50.
