Holiday Time Matching Family Women's Pajama Top and Pants Set, 2-Piece, Brilliant Red, Size S

I'm normally womens XL. The XL were pretty loose, but would work fine. Tried on my daughters women's medium and they work for me. Not loose, but not really tight either. I don't know if I want a medium or large for myself. For reference. I'm 5'5” 185 lbs. the green is the women's medium and red is women's XL in the pics. Men's medium fit me a tad loosely, how I expect the women's large might fit, but the men's sleeves are a little long on me personally. The men's small was a little snug on me, but doable. The sleeves were also a Lille long on me, but can be rolled up at the cuff easily. That's what I'm planning for my son that is shorter than myself. I hope this is helpful. Great pajamas!!
