I bought a Large size due to other comments about running too small. It fits just GREAT! Fits snuggly and is very flattering. However, it is somewhat looser around the tummy which is nice.
It is very comfortable. I like it. This is the kind of jacket I would like to wear almost every day and would probably get another one.
My athletic tops are usually medium sized, but with this, I could have gotten away with a large. It fits snugly but looks nice and is somewhat slim. If you like things to fit loosely, then size up!
I washed and dried my jacket and it came out looking brand new, so I expect they hold up well. I bought a large size and it fits perfectly. A great addition to my yoga wear.
I really love this jacket so I bought two of them. I wear these jackets over my yoga clothes. Actually, they are not heavy, rather they are comfortable and fit well.
