Vineyard Vines Mens Crosby Shirt

Lightly worn by son who went off to college a few years ago. Blue plaid with light green accent plaid. Very clean and like new. Casual button-down. Label says " Slim Fit Crosby Shirt", Size L. Not sure what "slim" means.....armpit-to-armpit measures 23". Which equals a 46" chest. Appears to be cotton material. Very clean. Note the very clean neck collar. Shoulder seam to cuff measures 25". (Our son is 6' 3" .....just to help buyer with context of sizing here.) We paid less than $100 a few years ago. VineyardVines.com shows similar shirts for $118, etc. (talk about inflation...!)
