My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly. The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.

Glad I switched

Super comfortable and have been very pleased with the quality and fit. It doesn’t feel like it’s made from one ply toilet paper which is great and doesn’t ride up. And for the price, I’ll be buying another set
