Adorable Kirna Zabete for Target dress size 8 never worn

It's super adorable but it's a little small for me in the boob area. I can cram em in but it's not great. This seems like a true size 8. I've only tried it on, never worn. The fabric is soft and stretchy with zipper front and polka dot detail. Very dark gray) charcoal. It's so cute.
