My barely 3 lb adult yorki poo is super hard to fit. Clothes fall off off him. He like his clothes because he gets cool even in the summer with the ac. The XS fits perfectly!. The sizing chart was Correct ! So many are not. Super soft and made well. My 2nd purchase in 2 weeks. About to checkout my 3rd purchase!My barely 3 lb adult yorki poo is super hard to fit. Clothes fall off off him. He like his clothes because he gets cool even in the summer with the ac. The XS fits perfectly!. The sizing chart was Correct ! So many are not. Super soft and made well.I ordered with my measurements in hand for my dog, somehow still got a little dogs outfit, seems like an XS to me. Don’t buy for medium dogsEven the Xtra Large didn't fit a medium sized dog. Be aware when you buy them. The fabric is soft but clearly polyester based so didn't stretch like others I have bought. All in all, not a brand I can use since my dog is large.This outfit is absolutely adorable! I have spent a lot of money at big box pet stores' clothing for my little Chi and they do not fit well at all. You cannot find PJs that she can keep on. As you can see, she is pretty small but also had a long neck. Most dog clothing items from the big box stores slide down her back towards her bum and we are constantly having to pull it back up. It is an absolute hassle. And if you don't catch their sales, you could pay a lot for clothing items.Besides big box pet stores, I have also shopped at a big name auction website and purchased many outfits. The fit on those were horrible as well. From the auction site, it's even worse because it's from overseas and therefore takes about a month to be delivered. Then, if you have to ship it back because it doesn't fit properly, that is another month to get back overseas and then another month to get the replacement item. Too much of a hassle.These PJs are so adorable and soft. They are softer on the outside than they are on the inside, but the inside is also soft. The legs are a bit long but the body actually fits her well. I purchased the small based on chest girth, length and neck rather than weight. If you look at the description for weight, it states she should be an XS (she is only 6lbs) but I found the measurements were too small for her.The colors are bright and the quality seems decent so far. Of course, she hasn't worn them for very long since I feel I need to wash everything before she truly wears them. I will update my review is something happens during the wash and dry or if the quality of the material or sewing turns out bad later. But so far, these are well worth the $10. I purchased two different designs and plan on purchasing more in the future after my dog has worn both for an extended length of time.I ordered an XL for my Pitbull, followed the sizing instructions and it was still WAY too small.Love itThis is definitely the best pj’s I’ve found for my Chihuahua. To get something long enough for her along her back they are usually huge and just fall off or trip her up. This fits perfectly and looks really lovely. Will definitely buy from these peeps again.I'm in love with these CuteBone pajamas. The fabric is soft and the dog hair doesn't stick to the fabric. They are the perfect fit for my pug and any other breed I've tried them on as they are adjustable with an elastic cord at the chest. My pug wears them every day because it cuts down on the amount of hair in the house and my car. Most importantly, my pug loves wearing them because they are warm but lightweight with just the right amount of stretch. I recommend these to everyone and I will never buy another brand again!!!My 6 lb. miniature poodle shitzu X has long legs and all the other sleepers I've bought leave half the leg bare. These are blessedly long enough to cover her legs. I love the elastic on the torso as it keeps her from wiggling out of the sleeves while she sleeps. Well made, soft to touch, but the fabric is not thick as such it adds extra warmth in the fall and spring, but I will probably need to add an additional sweater in the winter. She has a very thin fine hair not fur and gets cold easily. Plan to buy more.Love the feel and weight of the material. I ordered a size large to fit the chest measurement of my small shitzu and found it to be a bit too big. I would order a size down next time. Washed it a few times and holding up wellThey fit nice and are super cute. My only complaint is the back is a little short. I have bought others the same size and not had this problem. Next time I will try a larger size and hope this fixes the problem with them becoming too big elsewhere.
