A cotton bodysuit is the foundation piece that actually stays where you put it. Cotton breathes, it washes well, and it does not slip down throughout the day no matter what you are doing. The fit needs to be precise at the crotch and the shoulders to prevent any shifting. We have focused on neutral tones that work under everything from jeans to dresses to tailored pants. The weight of the cotton matters here. Too thin and it becomes sheer in all the wrong places. Too heavy and it defeats the purpose of wearing a bodysuit at all. These are the cotton bodysuits that prove simple construction and good fabric are all you actually need.
