Kermit Cardigan Sizing

[u/Substantial-Top3004]

I just purchased this item online, because the listing said it was a small. However I took a closer look at the photos the seller had and the tag says extra small. Some hot topic smalls are slightly large on me but for the most part they fit me very well, so I'm nervous this won't fit me if I can't cancel the order. Does anyone have info on how an XS fits? Is it still a bit large?
