My adorable romper is 40% off (20% promo, + 20% coupon). Use promo code 20DY3QTI. Promo expires 10/27 at midnight PST. I am an XS wearing a size small, and it is a good fit. Based on this and some of the reviews, I would consider sizing up one size. Click below pic to shop the romper. Other items from the reel are linked in the caption.
