Purple Candy Zippered Cargo Sundress w/ Pockets

So cute! Fully lined and with full-length zipper in front, low waist. Measures 15 inches across from armpit to armpit and 32 inches in length. Label says size 16 but that's definitely incorrect (maybe junior sizing?). I'm thinking it might be suited for a size 4. Please refer to the above measurements. 100% cotton. 0260
