My measurements are Bust: 39 in, Shoulders: 18-19in, Waist: 37-39 in, Hips: 42-44 in, height 5’5, weight 190lbs.
I am usually a size XL or 13/15 in everything. I got this dress in an XL, and it fit perfectly. It does have stretch to it, however do go with your usually size. The dress is super comfortable. Expect to wear heels with it if not, the long mesh tail will be touching the floor.
