Lace-Up Cutout Long Sleeve Cocktail Minidress

What a shame because the dress looks so flirty and fun but it's too small! I usually wear a size 0 or 2 and while I would ordinarily size up for a brand I've never tried, they didn't have a Small in stock. I figured the XS might work given it's not out of my usual size range but it doesn't even zip up all the way! The fabric has ZERO stretch. It would look fantastic on an hourglass shape in the right size.
