Very cute costume! I was so excited to wear it for Halloween, but unfortunately, it runs very small, so definitely size up. Since it was a final sale, I had to reorder a larger size, and even then, it still felt very snug. To make things worse, within a few hours of wearing it, the logo with the pizza peeled off on its own. Very disappointing. BTW I'm 5'2 and weigh 136 for reference I'm usually a size S/M

i sized up and it was still very tight. i could barely get it on
