What kind of dress is this? Posted on July 19, 2012 by Baday It used to be in fashion and my friends called it a babydoll dress. But when I look up babydoll dress on ebay I can not find anything that looks like what I want. They usually have wide straps, often with buttons where the straps join the dress. They are low cut, and you’re meant to wear a shirt underneath them. Often they’re loose. Anyone know what they’re called?
