Slip into a babydoll or chemise for an extra sexy treat. Both lingerie dresses look flattering on anyone. The only difference between the two is that babydolls have an empire waist and flow out loosely around the hips, while chemises are a bit tighter. Either one is the perfect match for someone new to lingerie. They offer a certain amount of sex appeal without putting too much of yourself on display — unless you go for an open cup choice — which is another sexy alternative.
