This is a handmade size 120 dress. It's the same size as another dress I have, and a different color^^ The collar is not removable. It has wrinkles because it was stored. I will iron it before shipping (￣▽￣;) My elderly mother made this as a hobby. This is handmade, so please understand before purchasing. If you purchase two or more items, the shipping method will change. ◼️Name◼️Address◼️Contact information is required! Please understand before purchasing.
