What is a plus size babydoll? It's really just a name for a nightie or negligee. The latter is probably more accurate because it conjures up the more sexy styling that a plus size babydoll has. Babydolls are generally shorter and more revealing than traditional nightdresses, though that doesn't mean that every plus size babydoll is outlandish. We stock a variety of plus size babydolls from various manufacturers in XL+ sizes from 18-26. As you can see from our selection below, a plus size babydoll is a lot more flirty than the standard nightie. With open front, fishnet and lace babydolls available, we have over 50 different plus size babydolls to choose from.
