No clue how this is the size its supposed to be. Im a size 14/16 and ordered a 2X. I couldn't get it past my hips or over my head. The waistband is extremely small. I don't know how they do the measurements because the sizing chart provided to me does not match the physical measurements. I checked. I needed this for a wedding I was attending and bought a matching dress in the same color for my daughter. Im stupid and didn't think to try it on and had to go shopping 4 hours before the wedding. I don't suggest this product.
