I love this dress! The neck and waist are super stretchy! You could have a larger chest and fall in LOVE with this because it will hug you right under your chest, in the best way! The draping over the pooch area is spot on too! It lays very well!
You can size down but you don’t need to! Anytime I say you can, doesn't mean you should! But if you’re in between and it’s available, you should! If only the medium were in stock, it would work because i just wouldn't use the stretch! That’s the case ...
