First impression, it is a great shirt. I was hesitant to purchase because of sizing concerns...products from them and similar brands tend to be too slim fitting for my taste. However, this shirt appears to be true to size, well at least American sizing. I typically wear a large and this one fit almost perfectly. Both neckline and length are perfect...can be tucked in or worn untucked. I am looking forward to wearing it with a blazer for a business meeting. It will also be great for a night out when I visit my favorite tropical vacation spot. I will definitely be buying more.

Check size.

Color: Navy Blue, Size: Large

I normally order a large. This was a little loose. Some may like that. Otherwise, it is a comfortable shirt.
