For reference- 5’3​,​ about 130lbs​,​ 34C​,​ usually a US size 4​/​small​/​27 or 28 in denim. Shella Dress in Polka Dots​,​ size 4. Really loved this dress. It does have smocking in the back where the zipper is. I know some people aren’t fans of smocking but as a nursing mom I love the flexibility it provides. Cute slit​,​ good movement and not too exposed.
