This dress has a half slip very little stretch to larger women I always tell don't unzip the dress to put it on if u don't have someone to help u, take your time struggle and it will fall in place I ordered my friend one and she had a hard time with zipping. I'm 5'8 240lbs Im size XL u will feel your absolute best in this dress confident paired with your best prefume I suggest black optium ysl now that's a 5star woman
