i bought a size up just in case this costume ran small, and it STILL was too tight! the costume has absolutely NO give in it, it's not stretchy at all. i think that was the main problem, b/c if it stretched i probably could have made it work.

this costume was made for skinny women and not a woman with boobs & butt like me. if you're skinny then by all means purchase away... but i returned mine. and i'm still upset i had to pay a return shipping fee of over $10 when the costume was like $26! ugh
