Black one piece bodysuit

Black one piece bodysuit. Brand New this was given to me as a gift as well and I cannot fit it. I look like a xs but I'm not lol. It's like a quilt type of fabric it's really pretty. It doesn't have a tag on it although it's new it was given to me from someone who thought it could fit it and couldn't and now I got it and can't fit it lol so Poshmark lets see if you can give it a try and fit it. Again it brand has been tried in but has not completely been on full body.
