  • Super-soft onesie pajamas
Color: Pink Penguin Size: Small
The product headline for these onesie pajamas currently calls them "adult" sized pajamas -- and based on that description and the measurements, I thought these would probably be way to big for my 9 year old daughter -- but she really wanted to try them out, and said she didn't mind if they were way to big, and she could grow into them... So, anyway, I ordered the "Small" size -- and they turned out to be a perfect fit for her. I mean, overall it's a super baggy, loose-fitting item -- but it's supposed to be. In terms of leg length and arm-length, it's only slightly too long for her -- and because the end of the legs and sleeves are an elastic materials, that keeps the arms and legs from drooping over onto her hands and feet, as the elastic correctly holds the sleeves and legs in place at her wrists and ankles... Actually, if you were ordering these pajamas for an adult, I'd suggest going a size up, because my daughter is a skinny kid and, although certainly on the tallter side, not extremely tall for her age, so if if the size small "adult" fits a nine year old, then I'd guess that this size would actually be too small for a lot bigger kids and even adults who might normally choose a size small. Anyway, my daughter is very happy with these pajamas -- she says they're super soft and comfortable, and warm but not too hot, and she looks very funny walking around the house dressed as a pink penguin haha. ... show more

  • Comfortable and fun, a bit small
Color: Pink Penguin Size: Medium
Oh man the kids loved when I put this on. They went crazy for the cute little tail. We had dinner all dressed in pajama costumes and it was super fun. Super. Fun. This arrived quickly and appears well-made. It's very soft and cuddly. I ordered a medium because I'm a small and I wanted to swim in the fabric a bit. It fits perfectly, so I wish I had ordered a large. ... show more

  • Cutest Pajamas Ever! I LOVE this!! ❤️
Color: Jump Jump Tiger Size: Large
This 'SWEETXIN' Adult One-Piece Pajamas are super cute, and are unlike anything I've ever had. 😊I love the character theme of the one I ordered; it resembles the Tiger character from Winnie-the-Pooh. ❤️ I like how there is a hood to this, which is not only comfortable, but also resembles the character's face. 🐯 The pajamas are easy to put on, and these fit great; they're roomy, and give me some extra space without feeling too big. Another nice feature of these pajamas is that they have pockets on the sides (they don't look visible); this is great for storing your phone and other essentials. I like that the bottoms of the legs are cuffed, and so I can wear whatever socks or slippers I want. The tiger tail on the back is cute, and adds more fun to the character pajamas. These are nice quality, and they not only are great PJ's; but could be nice for Halloween, for school spirit weeks, parties, and other things. I love these, and I feel so snug and comfy in these! For the current price of around $35.99, I think these are very reasonable in price for a full sized onsie like this. These could be a great gift to someone you care about also! 😊 ... show more

  • a fun costume for any time
Color: Black Cat Size: X-Large
SWEETXIN Adult Unisex One-Piece Onesie Animal Cosplay Costume is a fun outfit to wear at any time. It is not a thin material so can be worn in cooler climates, too. It has everything you need to complete your costume look. Here we have the black cat onesie and the tail is so adorable. The face is exposed so nothing to interfere with eating, talking or rubbing on skin. This is like a pajama in that you unzip it and step right in. The hood even had the ears for the cat built in. I've attached photos of my son imitating a panther. He will be wearing this for Halloween this year. ... show more

  • Soft & Warm
Color: Pink Stitch Size: Medium
I got the pink stitch to add to my collection of onesies. I got this in a medium because it’s unisex sizes & it runs true to size & fits perfectly. It’s super soft & warm. Really good quality & haven’t had any issues with it at all.

  • The cat’s pajamas — with pockets
Color: Black Cat Size: Large
I like these pajamas with a cat hood. They make me smile. The fabric is soft, comfortable, and lightweight. Best of all, these cat pajamas have pockets on both sides. The cuffs and are all elastic. The fit (other than the cuffs) is loose, which is something else I like. If I wanted to wear this as a costume rather than pajamas, I could, and it’s loose enough to go over other clothes. Finally, I love the embroidery on the hood of the cat’s eyes. ... show more

  • So soft
Color: Panda Size: Medium
This Panda suit is so comfortable. It has little panda paws on it and it seems to be very durable. It’s so cute and fun, I almost want one for myself. It fit perfectly.

  • SWEETXIN Adult Unisex One-Piece Onesie Pajamas Cat
Color: Black Cat Size: Medium
So much to love about this! It's cuddly soft inside and out. It's not at all uncomfortable or itchy. I love the dual colored eyes on the little kitty hood. It's overall well made with a good zipper and a cute tail. I'm very happy with almost everything about it actually. I wish the legs were a bit longer. I'm 5 foot 5 inches tall and I've got significant ankle/calf exposure which I don't love. I wish they fit baggy in the legs. But aside from the vertically challenged friendly aspect, I'd say these are a good buy. Especially if you're on the shorter side! Would recommend. ... show more
