This was a real surprise. It was my first order with DC and I wasn't sure about sizing. I'm 6'1, 185lbs and I'm often in between size Medium & Large. Based on the sizing instructions, I went with the Large in the olive green color. It just arrived and I tried it on. Love it. It's a great color and pattern and very stylish. I'd call this a "slimmer-fit" shirt, so bear that in mind when ordering. I often complain about shirt-length and sleeve-length, but not with this shirt....plenty of room on both counts. If you're a bigger it may be too snug of a fit for you. It's also more of a light-weight corduroy, so not overly warm. I plan to wear with a t-shirt underneath and a pair of jeans. I haven't washed it yet, but based on the other comments, I'll be careful to either hang dry or dry on a low heat. It's a keeper......and a great deal.
