Fine for a pajama top

It's a little thin, and runs very large. I wear it as a pajama top in the winter, so I'd prefer it if it were a little heftier.

The Karen Neuburger Women's Long-Sleeve Girlfriend Pajama Set I got in a size larger than I typically would because I wanted a baggier fit instead of a more form fitting fit. I'm nearly five foot three inches tall and weigh around 125-130lbs. Depending on the brand can wear anywhere from a small to a large. Since this is a petite sizing , I knew even though it would be baggier it would fit just fine in height and I was right.

The elastic waist band isn't constricting and doesn't roll like some bands I've come across. There's no tie for adjustment but I didn't find the pants to need it. The sleeves are perfect not being too short or too long. The buttons are sewn on well. The v-neck isn't too deep on the top. The collar stays in place without curling up. There's no loose stitching to speak of. These are made quite well. These pajamas are comfortable. The material is soft and hasn't caused any irritation to my skin. They are easy to keep clean and I haven't noticed any fading.

The warmth level is moderate. These can be worn year round depending on warm or cool you keep your home. If it's winter, you could pair these with your favorite camisole for another layer to keep a little warmer. If I get to hot I just loose the top and wear the pants with a sleep tank top.

 These are nice to wear in evening before bed and good for sleeping in as well.  A modest choice for evening wear if my kids are having a sleep over or if we are out camping and I don't want to get fully dressed just to go to the bathroom. I recommend these. They run true to size but if you want a looser fit like I did, just get a size up or two.

Comfortable and cute pajama set. It fits nicely, but shrunk a little when washed. The pants are a bit thin and wish they were a bit softer.  I would buy them again for the price.

The pants fit as expected but the top ran a bit small (I have a feeling it'll be too small for me once I wash it).  This is a very soft, very warm set of pajamas.

The pajamas are very comfortable. However, the waistband isn't the best I've ever worn, it doesn't cinch as much as I hoped it would. It's both elastic and has a drawstring. Additionally, the legs of the pajama pants are just long enough when I'm standing, and ride up a bit when I sit. I'm 5'6" so these pants will likely be short on anyone who's taller than that.

I use these shirts as pajama tops and they are very good for that purpose and reasonably priced. The material is very comfortable and much better than cotton because it gives with your movements and doesn't bind. After trying one shirt I ordered two more.

My kid live it and it is a nice fabric? The cape is a plus... Shoould not be used as pajama as the Velcro wears out fast

I would not wear this T out of the house but it is fine for lounging. And at the price..that's what I bought four of them for.

Good pajamas.  It's comfortable to wear.  I didn't give it 5 stars because it's not outstanding (i.e., set apart from anything else), but you will be satisfied, just ensure you get the correct size.

Fit is okay, would prefer not so loose around neck area but good value

I don't care for the neckline on the top.  I had to cut it into a scoop neck so I could breathe.  Soft material, comfortable for under clothes or as pjs.

Fine, so long as you wear something overtop it.  It tends to show padding lines in the rear.  Very tight fit in front.

Well, I assume it fit as expected -- It was a gift I sent to my Dad and I also wish I had read the reviews because I also thought this was a pajama SET - and just had to order the bottoms to go with it -- Which brings these summer pjs to over $40 -- Not what I consider a bargain by any means, but .... it is what it is ... I just hope the pants actually ship in two days.

Super comfy pajama pants.  Not the highest quality but what you would expect given the price.  The best is that they are long enough, hard to find in pajama pants.

Goes great with my grouch pajama pants.  Grouch is a bit smaller than he looks on the photo (bought size XL).

Fit was very loose and fabric was very thin. it looks and feels like a pajama top. That's what my husband is using it for.

They are fine.  A little too loose fitting for my liking.  I prefer a bottom sheet that fits tight!
