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.

Nicely Made Shirt
Color: Blue 1, Size: Medium
Linen is always nice. This material does not easily wrinkle. The material is think but not see-through. It is not an athletic fit but fits well on my very buff son. The size is correct for what I normally order for him. The color is more pail than in the picture, but that's to be expected with linen. We have purchased 3 more colors.
