I've always wanted to put my boyfriend in footed pajamas and did research for few months before Christmas over from which website I have to get one. I debated a lot about which size to order, but none of the previous reviews was descriptive about it. I ordered medium and it was a perfect fit. My boyfriend is 5'11" and his chest is 43. When laid flat, the chest of size medium is 46. The seller's description of item was correct, and not only that, this feety suit is really well-made. Fabric is soft, design is great, and the detachable feet part is really well made and the whole suit doesn't look cheap at all. I'd like to order one for myself but my size of female footed pajamas were all sold out. I recommend this product to everybody who wants to stay warm in a nice and cute sleepwear.
