NWT J Crew Wren slim shirt in Baird McNutt Irish linen Small petite One of the latest additions to our shirt collection, this style is just the right length to tuck in without any bunching. Plus, it's made with linen from Ireland's Baird McNutt mill (Irish linen is considered to be the world's finest, and Baird McNutt's is the finest in Ireland) and it has an incredible softness, thanks to a weaving process that the mill has been perfecting since 1912. 100% linen. Machine wash.
