I normally wear an xsmall or small and ordered the small jacket. Firstly, I didn’t realize it was cropped. Secondly, it was so short and small. It fit but was snug and so short it looked like I was wearing a child’s jacket. I’m 5’5” with a high waist and short torso. Tried a medium in the light and dark color. I could tell as soon as I looked at the medium the cut was much better for me: Longer and bigger. When it’s buttoned it’s still roomy and easy to move. The sizing isn’t exact. The size medium dark jacket was bigger than the size medium light jacket. They both fit but differently. After getting the size right I’m really happy with this jacket. Nice piece for the price.Update: I ordered another light jacket in medium and it fit like the dark. To recap, the first light jacket in medium was smaller than the second light jacket in the same size. Sizing isn’t consistent every time but I’m getting a lot of use out of both colors and am very pleased.
