Other than the description on the site tells you this item is rather ralexed and a bit oversized. so if you want it fitted you might size down. The collar is very wide, too and looks a bit weird if the top button is left open - it looks best buttoned all the way up and I think it`s intended to be worn that way. It looks great, though and is very comfortable and light to wear - probably more suited for spring and summer. I really like the large silver poppers because they perfectly match the design and make this shirt unique and stand out of the crowd but there might be a problem with them: The flannel is too light for the rivets and they tear out if you aren`t careful enough - so it might be wise to use a double layer of fabric at the button placket or make it otherwise stronger. But other than that it`s a stylish shirt with really cool features.
