Couples Matching Onesie Pajamas - Cozy Bodysuit for Couples - Home Loungewear for Date Nights & Relaxing Together

I like the onesie, but it seems two sizes smaller than other adult onesies. I got a Large, which usually has ample room with other brands. This one seems more like a Small. It has "L" on the tag, so I didn't just receive the wrong size.I'm 6' 1" tall and 160 lbs. Very skinny. It's actually quite skinny on me, which is okay, but i can barely get the snaps closed. Very tight. And this is before any washing/shrinking.
