It's a size M. I only tried it on once. It's listed as size M, but it's a rather loose-fitting bustier. I'm selling it at a low price because I bought another bustier. Camisole Zara Available for immediate purchase. I will take measures to prevent water damage when shipping. I've set the shipping time to be longer, but I will basically ship it within two days. #bustier #Zara #ZARA
