This dress is adorable but like most dresses with zippers that this company sells, it runs very small in the chest both in measurement and in fabric coverage. I’m normally an XS from Hill House and wear a 32G bra and this dress is way, way too small across the bust. It fits fine otherwise. If you’re even somewhat fuller busted, I would definitely size up. I love Hill House dresses but find the sizing is extremely inconsistent across styles.
