Distressed Plaid Button-Up

Distressed/bleached blue plaid top. New without tag; never worn/washed. Tag says Medium, but fits more like a Small. First two photos were taken with natural outdoor lighting; third photo is with indoor lighting. About 17" across chest and 23" long. (Purchased new with tag, but it's a little too tight for me to layer. Unfortunately I have a chronic condition that forces me to remove tags before trying on.)
