This 2 pc., Ink & Ivy creation is one of my favorite jammies to wear. It feels soooooo good against my skin. The material of both pieces feels like heaven to wear. I’ve worn mine most of today, lounging & working here at home, and getting some sun out back. It has the best of both worlds. Superb comfort AND style! The colors are POPPING & brilliant. I love this fit for sleep and at-home play wear. DO NOT SIZE UP! If you want it a little more fitted then my photos, you can size down, and there’s so much stretch, you’ll be just fine! Plus, the elastic waist has a drawstring. I have (at the smallest part), a 26.75 inch waist, almost 27, and I have to really tighten it up to nearly the max, so if they had XS.. I’d be great in that, but I’m still a huge fan, and it does work for me. I marked it somewhat large in comparison to another size small set like this that I received from them. The shorts seem a tad larger at the waist, but they stay up.. I’m just very thorough in my reviews. Small works.. XS would work too. I don’t believe that’s an option. Any smaller then myself like under 26 inches, a small may not work that well, or at least would be lower rise on you. It still would do the job, if you don’t mind that. I’m 127 lbs. (today :). ** Nooo booty cheeks will show. At least at my height. I am 5’6’’ tall. I added a pic of the length. It’s A+. Thick ‘WAY’ upper thighs are hidden, lol.** ANYWAY, love, love, love it! The price was $29.99 with a 20% off discount coupon (now..it may not last.) That is at the time of my review. To me, it’s reasonable enough for this frugal mama. That’s how much I do love everything about it, as I shop a lot, but let’s just say it.. I’m cheap, but like nice stuff lol. Summer is here ladies! Enjoy & relax in comfort. You deserve it! 5 stars! ⭐️⭐️⭐️⭐️⭐️ **I hope that my review has been helpful ????!**
