Comfortable fit, but the pattern looks a bit dated
Size: XX-Large, Color: Dark Green Stripe Knit
I grabbed this in an XXL looking for a comfortable, breezy shirt for the summer. The actual fit and feel of the shirt are really nice. It's a true relaxed fit that doesn't pull tight across the chest or stomach, and the knit material is surprisingly soft and breathable, kind of like a lightweight summer sweater. It definitely doesn't feel like stiff, cheap cotton. My main issue is just the design itself. I ordered the dark green stripe, and in person, the pattern just looks a bit dated, almost like a retro bowling shirt or old upholstery rather than a modern vacation button-down. I'm not the biggest fan of how the stripes look on me, so it has basically become a shirt I just wear lounging around the house instead of actually wearing it out anywhere nice.
