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.
