So much better than the photos 👍🏻
Size: Small, Color: Pure White, Size: Small, Color: Pure White
The photos for this jacket really had me worried but I took a chance. I was hoping for a crisp white. It a good solid white. Not cream. Quite lightweight so if you like to layer and would like a hood for light rain or snow this will do the trick. I buy men’s jackets because the sleeves are longer and these were perfect. And I’m short waisted and it was easy to roll the bottom under and it stays put. I was very pleasantly surprised. I got a medium and I’m 5’7”, 125. Perfect fit. Well constructed too. No tightness in the chest when I swing my arms back.
