I bought a Brooks Brothers glen plaid sport coat at the Housing Works Thrift Shop (143 W. 17th Street in Manhattan). The design is a 3-button, natural shoulder sack cut. I’d say it’s in the range of 10-15 years old; but it’s in great condition and shows few signs of wear. Price: $10.00. It’s also an excellent fit (43 regular) and requires only one minor alteration: having the collar lowered in the back. There is a slight ridge just below the collar that my tailor can take in and make perfectly smooth. That work usually runs about $12.00. This coat would go with khakis or gray flannels and an ecru button down. It occurred to me that this could possibly be an orphaned suit jacket, but it really doesn’t seem like it.
