This costume is so cute! It has a plush little fat belly! It seems like it'll be really warm. As for a lot of costumes, I'd size up when in doubt. I got the 4 year size for my newly 3 YO and it fits perfect (he's skinny and a little tall). I only wish the tail was a tad shorter or it had wire in it to make it stand up because I think it'll drag on the ground. Oh, and the mitts are a really odd shape and they should have made the booties with the elastic on the underside so you could just stick them onto the kids outdoor shoes instead of making an actual bootie! Would recommend for sure!
Bottom Line Yes, I would recommend this to a friend
