This is a long-sleeved shirt with an overall sheer look. The collar and sleeves have lace detailing. Size is marked as M, but the back is very long and loose-fitting. Wrinkle-resistant. Can be tucked into skirts or pants. Why not have fun with your innerwear? It hasn't been worn often, so there are no noticeable stains, but please understand this before purchasing. Formal, black, office, presentation, antique, vintage, retro.
