REVIEWS
I absolutely love this shirt. I get so many compliments every time I wear it. Navy is my favorite and I also have the black. Both look sharp whether I'm at a dinner or just out for a casual day. The stretch fabric keeps it looking crisp all day without ironing. I'm definitely grabbing a few more colors.
VerifiedSeptember 26, 2026I'm 6'1" and 205 lbs, and a lot of sweaters make me look wide. This one has a more tailored look without being tight. Feels comfortable sitting at a desk all day.
VerifiedSeptember 24, 2026Amazing shirts. I ordered three (black, gray and green) and was not disappointed. As someone who is usually skeptical of social media ads, these shirts were way above my expectations. Amazing fit, comfortable and a great look. Would highly recommend.
VerifiedSeptember 21, 2026Ordered for my hubby. The fit was perfect, comfortable, simple but classy and the material is great. Need more colours in this!
VerifiedSeptember 18, 2026These are actually decent quality shirts. Soft, stretchy material, and I like the little pop of color in the collar area. It gives it a more upscale look. They fit me a little loose but still good enough. Nice enough to wear to work and sporty enough for a round of golf. For the price and the material, I think this is a decent value.
VerifiedSeptember 14, 2026Great everyday shirt. Not too casual, not too dressy. I can wear it to the office on casual Fridays or out to dinner and it works both ways. The fit around the chest and shoulders is really good.
VerifiedSeptember 9, 2026My husband searched forever for a shirt to wear for our wedding. He has a wider chest and anything that fits his chest and shoulders is huge in the middle. We even bought an expensive "athletic fit" button-up from a specialty shop and returned it because it didn't fit. In a last-ditch effort I ordered this shirt and it was PERFECT. The fit was great and the material is so light. It was a scorching day when we got married and he said he was comfortable the whole time. Highly recommend!
VerifiedSeptember 3, 2026Gave these to my son and they fit perfectly! Love the colors. We got the white, blue and purple and all three are exactly as pictured. The detail on the collar adds a flair and makes them look almost designer. Lightweight, true to size, and they go with almost any pair of trousers or shorts.
