I initially ordered size Medium, but it was huge, particularly across hips and back. I ordered size Small and the fit is perfect. I can easily wear a lightweight top, but not a chunky sweater, but since jacket is super padded, I donât think Iâd need heavy layers. For size reference Iâm 5â 7â 36-26-36 130 lbs, Iâm a tad chesty with slim back, and I always have problems with jackets fitting on chest, but lose on hips, not with this jacket, size Small fits fine across bust and nicely on hips. With regard to color, I do love the blue, and the style of the jacket, especially all the hidden pockets. The only thing Iâm not fond of is the hood as is huge. I included some photos to help others in terms of size.
