DON'T LISTEN TO THE SIZE CHART! According to the size chart a 4X would equate to a US 16, which is my normal size. (The size chart doesn't even go that high and stops at XL so I just added to it.) Since the "chart" was off I ordered the 4X & it was WAY too big on me. So I decided to order two more sizes (3X & 2X), the 2X fits PERFECTLY!! I'm normally a 16 in pants & can range from a L to 2X, so I'd say it runs a bit small but most "women's" sized fitted shirts I'm usually a 2X.My measurements:Bust: 40 (around the widest part of my bust)Waist: 35 (around the smallest part of my waist)Hips: 48 (around the largest part of my hips, booty included)I'm very much a pear and this shirt fits my body so well! The design is adorable & very sparkly! I can't wait to wear it during my bachelorette weekend!
