Blonde Girl Reveals Her Red Chemise On The Beach In The Sea

As lingerie, a chemise is similar to a babydoll, which is also a short, loose-fitting, sleeveless garment. Typically, though, babydolls are more loose-fitting at the hips and are generally designed to more resemble a young girl's nightgown, although many modern styles have added various sexualizing features.
History
The chemise seems to have developed from the Roman tunica and first became popular in Europe in the Middle Ages. Women wore a shift or chemise under their gown or robe; while men wore a chemise with their trousers or braies, and covered the chemises with garments such as doublets, robes, etc.
