First off, these are awesome (at least as far as I can tell from having worn them for 5 minutes). They will be my second pair of footie pajamas as an adult, and already I prefer these to my old pair from another company. The feet fit FAR better, and the drop seat is a FAR better design than the flap style of my previous pair. The fleece is comfy and warm, and they seem well-made. I would probably prefer more of a cuff at the wrists to keep the cold air out, but it's not that big of a deal.

The only thing is that the sizing is a just a wee bit off. As of now--I'm hoping they'll adjust it--size 3 is listed as fitting people 5'0" to 5'3", and size 4 as fitting people 5'4" to 5'5". I would suggest they change the range for size 4 to 5'3" to 5'5" to indicate that there's a judgement call to be made by the buyer. I am precisely 5'2.5" and since the ranges are so narrow I thought they must be very dialed-in. I will grant that when standing up in them they seem like a perfect fit, and even when sitting with my feet on the floor they are still comfortable, but when I put my feet up, they pull at the bottom of my feet. Since I bought these in part to wear while lounging around with my feet up, I want them to be 100% comfortable while I'm doing that. It's a slight enough pull that I probably would have kept them except the description says they may shrink up to an inch in the wash. Probably in this size it would be less shrinkage--the full inch is probably for the larger sizes--but since it's already pushing it on comfort I decided to return them and go with the size 4. I was very sad to take them off because even so they are quite cozy, but I figured it would be gauche to lounge around all night in PJs I planned to return.

As for fit otherwise, the 3 is very good for me. As I said I am under 5'3". I weigh about 130 lbs, have 39" hips and wear a 32B bra. I was surprised at how slim they look on me while still being very comfortably roomy; my old pair was super baggy even though they were the right height for me. For someone about my build but with a C cup, I think these would still be quite roomy enough in the chest. Probably a D cup too, but I'm less sure of that. Someone with slightly broader hips would probably find these comfortable, but with significantly broader hips, you probably want to try a larger size. I wear size 7 shoes (5 in men's), and the feet are plenty roomy without being floppy like my old ones were. I feel pretty confident they would be comfortable for someone with a shoe size up to 9.
