Aritzia Connor Coat - Light Grey XXS

Bought this on here only a couple weeks ago and loved it but sadly, the XXS is too small for me :( ! I am 5’4 and usually 105-110lbs and (previously) would fit into 00/0 and xxs/xs in clothing. Unfortunately, I didn’t realize I had gained so much extra weight since the summer ended…now I’m 120lbs and not thinking a few extra pounds would make a difference, the XXS is now too tight on me. The condition of this coat is excellent - previous owner only wore it a handful of times and there are no signs of wear, pilling, stains, defects, etc.
