I’m 5’3, 100lbs, normally wear an XS, and ordered an S. It fits pretty well, but the top is longer than pictured and looks a bit odd, so I tuck the bottom of it into my bra which looks much better. I use the drawstring to keep the pants up, which works well.
The material is light but drapes well, and isn’t sheer. It arrived with some creases in it, but they came right out after a steaming. Cat hair doesn’t stick to it.
Overall it’s a very cute and unique outfit.

This is a super cute outfit, and fits really well - true to size. The pockets are a great addition. The material is soft, washes well, and dries well on low. I wear this to lounge around the house, but also looks cute to wear out and about. The best is it's lightweight which is great for warmer weather climates.

I am very pleased with this set. It’s super soft and cozy without any bulk or weight. It washes well. I'm 5'1" 120lbs and ordered a small. The top is baggy and fits my small frame exactly how I wanted it to, without the arm length being way too long. It is made with quality and isn't like most products that are cheaply made and falsely advertised. I would buy another one.

This two piece set is super comfy! I was a little worried it may make me too hot, but I was surprised to find it was cozy without adding addition heat during the summer time. The pants were a little big on me, but I liked having the top be a bit looser - and it did have an elastic waistband so it wasn't too bad. The inside isn't necessarily soft like a fleece, but it is not scratchy at all.

Bought it for my mom who lives in Finland. She has never been big on this style nighties but the first night she slept in it she was hooked in the comfort and softness of it. Most importantly, it is breathable and Cute! Getting myself a set next and most likely more of for gifts! Definitely a great gift! As long as you know the person and their likes :-)
