35% cotton shirt, 25% linen suit
Color: White, Size: 6, Color: White, Size: 6
This formal suit is not as white as I thought it was going to be. It’s off white due to it having 25% linen, which gives it a natural, “more expensive” sort of look. My 5yo said “it’s a little itchy but looks nice”. I think it’s just stiff because it’s new. I’m going to wash the button shirt and see how it is after washing. I do wish it was 100% cotton. The button shirt is made of a cotton blend with 35% cotton. The stitching is very clean. Well made. As you can tell, it’s a little loose on my average size 5yo. I got him size 6. This will be a great suit for one of the kids piano recitals.

Soft and comfortable
Color: Light Blue, Size: XX-Large
Soft material that fits nicely and the color is great for summer. Longer than my husband likes but that’s ok. Will likely purchase additional colors.
