I am a small woman. I wear a small in juniors and an XS in womans fashion. but this junior size jacket small was more like an XS. I couldnt zip it up over my bust.. And I dont have much of a bust to begin with. So I returned it to get a M. not true to size. I thought that the zipper was a bit cheaply made also.. but I still liked the jacket. Seemed warm and not as cropped as it looked on the manicans.
