Polka Dot Spaghetti Strap Summer Dress with Ricrac and Lace Trim

Super cute polka dot dress with spaghetti straps. Light taupe background with teal, light blue, and brown polka dots. Lace trim on wrap-style top. Fitted to under bust then slightly a-line. Fully lined, back zip closure. Listing as a Small even though tag says size Medium- there is no stretch and I'd say it fits more like a Small, especially across the bodice. EUC, worn only once. Approx measurements: p-p 15" under bust (at ricrac) 13" waist-ish 17" underarm to hem 27"
