There are two types of pajamas—sleep jammies and lounging pajamas. I was looking for sleep jammies and am excited that I got both in one pair! These are super comfortable, not too tight, but certainly not baggy. They’re cute in a bit of a nerdy way with stars of all different shades (much nicer colors than in the pictures!!!) and sizes on a pitch black background. Very unique look. At first touch, I was afraid the fabric might be “sweat-inducing” but it is absolutely not, even with my heat cranked up in my house, and the fabric feels silky smooth, like satin, only a little thicker. I like that it’s not thin because it provides some modesty-coverage if needed. (I don’t feel like I need to wear a bra underneath). And they feel like lounge pajamas because they have pockets!—but since the fabric is a thin fabric (a good thin, not a bad thin—it feels very high quality) the pockets don’t feel bulky and won’t get in the way if you’re a side sleeper. The cuff material on the ankles, wrists, waist, and neck is high quality, and the stitching on all is ***very*** well done. I am so impressed with these jammies that I ordered a second pair for myself and am thinking of ordering some for Christmas gifts. As for fit, I’m 165lbs and 5’7” and I ordered and xl. The top is a little loose, but the waist is just right. Overall, I like the fit and would choose to have the top a loose fit. They are going to keep me nice and cozy warm this winter when it’s cold outside! And they’re perfect for lounging all fall.
