Never worn Lilac Corset Midi Prom Gown US 4

I had this gown custom-made to my measurements, but when it arrived, it was a bit snug across the bust for me, and returns were seemingly a nightmare. This has never been worn except to try on, it’s brand new. Any wrinkles are from being shipped and will come out with light steaming. (Not too close!) The material has sheer layers on top, with a thicker layer on bottom to avoid being translucent. The bodice has some light corset boning through it, and the belt features a metallic diamond buckle. (Not plastic.) The straps feature a unique shape, flattering your shoulders and collarbone. Mesh between the bust gives you a feeling of extra security. Fits like a size 4. 34 B 44” from shoulder to hem 30” from waist to hem 26” waist I am open to offers.
