I am size 34-36 in jeans and the XL size fits good, almost a bit to big in the waist but I fear the L size would be to small. I will be keeping the XL, they are fine. These are very comfortable, almost like wearing nothing at all. After 5 minutes you don't even feel the thong. Material feels great against the skin and these wash and dry very fast. The pouch is a bit to small but the material does stretch a bit. The free returns option is great even though I didn't need to return. I would buy again.
