Thank you for viewing. This is a ladies' formal dress (Igin). The size is 15. It has a collar, but it seems to be removable (it's not firmly sewn, more like a temporary stitch - please check photos 11-13). One point of concern is a small stain on the white collar. It was worn once or twice, then dry cleaned and stored in a closet at home. Please refrain from purchasing if you are looking for a new item, as this is a used garment. A formal dress featuring a white collar and a pleated skirt. - Color: Black - Design: Pleated skirt, long sleeves, buttons, belt - Collar: White collar - Style: Formal, one-piece style Thank you for viewing.
