M&S Navy and White Gingham Skirt Suit (2pc)

I ordered this pair (Jersey Gingham Edge To Edge Blazer and Gingham Fitted Pencil Skirt) from Marks and Spencer in the UK but never got around to having it shortened and now it is too big for me. The suit is made from a knit fabric and features ribbon banding at the collar, placket, and the two faux front pockets. The jacket closes at the collar with a single hook. The straight skirt has an elastic waistband and a small slit at the back. Both pieces are marked UK size 18 (US size 14). They were never worn and are in new condition.
