Retro-look Patterned Blouse

Blouse with a red and blue checkered/diamond/idk what to call it but it gives me 70s vibes pattern. Target/Merona brand, size small. Keyhole back, fitted in the shoulders and loose at the bottom. A little dingy in the armpits but very well hidden by the pattern. Why I’m Selling: Didn’t quite fit me in the shoulders last time I tried it on (it may fit now) but nowhere to wear it and 100% polyester not great in Florida.
