Looks great, however had size issue
Color: Blue, Size: Small
I ordered the small, however the sleeves were too long and will return it. The shirt looked great and seemed to be of very good quality. Certainly would have kept it if not for the sleeves.

Excellent!!
Color: Beige, Size: Large
Really loved these shirts for my hubby. They were pretty good quality shirts. Love the linen material. Also love the buttons on the collar which my husband prefers to wear with his jackets. They are very comfortable. As far as size, I ordered according to the size chart. He typically wears a size Large. According to the size chart an XL would best so that’s what I ordered. But I truly believe that a size L would’ve been better. So I would say they are true to size. My husband weighs 205, and has muscles and a size L would’ve been just fine. I ordered 3 because I loved them. I’ll stay with the XL. But if I were to order more I’ll preorder a Large. Very happy with this purchase. They are not slim fit either. Just for an FYI.

Quality + Fit + Value - VERY pleasantly surprised!
Color: Black, Size: Large
I stand at 6.0125" 200lb (showing signs of a Dad bod)., and the large was a perfect fit for me. The quality exceeded expectations, perfect thickness and weight for the colder months. I actually set this up between a Boss & Ted Baker (my-go's to in past 10-years) and asked my date to pick one of three - she grabbed this shirt. if you're looking to re-evaluate how much your spend on dress shirts - this Brand will not disappoint in terms of quality and fit. If your wearing brands like Express, Banana or even worse - Untuck-it, consider this a marginal upgrade. I'm going to by a few more and I'll update if anything changes.

Great shirt
Color: Beige, Size: Medium
Great fit, seemed like thin to medium weight fabric which is perfect for him. Lil with any linen blends, they wrinkle so it is more of a casual wear. Washes great and is super soft when wearing.
