I purchased XL based on one review left stating that the dress had little stretch. GIRLLLL this thing has not one INCH of stretch. I would literally need to buy a 1X for it to zip maybe even a 2X for it to fit comfortably. Mind you I’m 5’5 DD and normally wear size Large. I love the dress it’s beautiful and has a side zipper but unfortunately I will need to buy another size and cross my fingers it fits.
