I am cleaning out my closet of a lot of my business casual attire as I no longer need it for work. This is a blue plaid button up dress shirt from J.Crew. It is a size 15.5 and 34. The Ludlow shirts from J.Crew are a more tailored cut. This shirt is non-iron, which is great for a work shirt. Please feel free to send me any questions you may have or if you would like additional photos.
