20W LBD with Mirror Buckle Waist Detail

Super cute, zipper-less LBD with metal detail at waist. This by New Look Inspire. It has never been worn. It is a UK 24 which is a US 20W. It is more of a body con or fitted dress. Shoulder to shoulder: 11.5” across. Pit to pit: 21” across. Length across metal buckle under bust: 19” across. Hips across: 22” I’ve attached the size chart from the brand. All measurements taken while flat.
