I wore these during my pregnancy because they were made of elastic. After giving birth, I was originally a size S, and I'm not sure if my body shape returned to normal or if the elastic stretched a bit, but they feel loose, so I'm selling them. Please check the photos for the condition of the elastic. Strawberry-patterned long-sleeved pajama set, 100% polyester. There are a few small, inconspicuous snags. There is a yellowish spot that is not very noticeable, so please check the photos. I have included photos of the snagged areas, so please refrain from purchasing if you are looking for a perfect item. I have priced them lower accordingly, so please understand. - Brand: GU - Size: M - Material: 100% Polyester - Design: Strawberry Pattern - Features: Long sleeves and pants set Thank you for looking.
