Princess Polly Milkmaid Top

Want to keep this so bad but the warning is: THERE IS NO STRETCH. I have worn this once and I am obsessed with it and made it work but I felt like if I ate anything I would pop a button so yeah, I need a size up Obsessed otherwise, it’s as cute as you think it’s gonna be If you happen to have this top and need a size down I would be down for a trade!!
