NWT black ribbed one shoulder crop top

Black one shoulder crop top from H&M. Worn only once to try on and realize it’s too big for me. Tagged as an M but really fits more like an L/XL or would be better for someone who is a size M with a larger chest. It looks like it has two straps but they’re sewn together at the top to hold them together - super cute look for a night out! Also very soft material and has a ribbed look to it.
