I bought a dress that is a "ballroom" style, so the skirt puffs out. They sold me a puffy slip to wear under the dress to make the skirt even bigger. But the thing is, lately I've been trying it on and I don't know if i want to wear the slip, i think it looks nice without it, and I don't want to take up a bunch of room in the dress... not to mention it will be easier to sit at the reception without the slip.am i SUPPOSED to wear it? like will anyone know that the dress is supposed to have a puffy slip?
