Woman's 3/4 sleeve black and turquoise pullover top

I absolutely love this top but it fits too tight across my stomach. It is XXL, 100% polyester. Black and turquoise color with criss cross design at the neck. Black on top with points down into the turquoise. Brand new, never worn. length is 25", sleeve length 19 1/2" armpit to armpit 21 1/2"
