Nice shirt. Wrinkles alot.
Size: 4X-Large Big, Color: Light Grey Vertical Stripe
Like the style and construction of the shirt. Fit and finish are as expected. Unfortunately the fabric wrinkles easily. Definitely requires ironing. Wish this shirt was a wash and wear but it's definitely a wash and iron before wearing shirt. Otherwise I have no complaints. Fabric is lightweight and could be used in summer as a dress shirt.

Very nice shirts
Size: Large, Color: White
These are a heavier fabric than I was expecting but that’s fine since it’s winter. They barely shrink being washed in hot water and dried in a hot dryer. I was actually hoping that they would shrink a little more after losing 40 pounds. But they shrunk just a little and they fit just fine. Also, if you take them out of the dryer immediately there are very few wrinkles.

Dress shirt
Size: XX-Large Big Tall, Color: Powder Blue
The material is a nice quality and the color is very close to the picture but I think it’s a bit darker in person. It definitely doesn’t fit like a “tall” should though but I think if we would have sized up it would have been to big. Overall it was an ok purchase for what we needed it for but it is a bit short.

Fit check = great
Size: X-Large, Color: Light Grey Vertical Stripe
Happy to finally find a great shirt fit for both business and casual looks. This shirt line is made in Sri Lanka (not Bangladesh). It has a great fit around the shoulders and chest for a 40 year old American male. It fits true to form and was recommended to me directly by Grok AI based on my exact waist, chest and neck measurements. It doesn't pull tight across the chest, and fits really nice with a sport coat. It's comfortable and breathable, the fabric is thick and high quality. You can wear this tucked or untucked depending on the attire you need. I bought 2 and will definitely buy the rest of the color line up. I'd love to see more colors and patterns available in this fit.
