I kid you not.
Garland is about an hour east of Fayetteville (map here). Owned by Brooks Brothers, the Garland Shirt Factory has been making the classic oxford Polo for... a really long time. I'm still waiting to hear exactly how long. Back in the '90s, I insured a number of apparel manufactures in the southeast. Most of them are gone but Garland drives on.
There's a unique outlet store in Garland. It's on the right as you come into town from the south. Just across from the Piggly Wiggly. Don't look for your typical '346' outlet. This one is refreshingly authentic. Last time I visited I saw 50 pair of dinner trousers (US made-pleated) and at least eight pair of white buck wingtips - all size 12.
There was a lotta outer wear. I secured a Blackwatch plaid Husky jacket for $35. And there were a fair amount of MTM monogrammed shirts. I asked a saleswoman if there were any oxford button downs. She sighed, "No, sir. They don't make many mistakes in the factory anymore." This video helps explain why.
Update: Brooks Brothers did a lotta digging and have advised the Garland Factory has been making the Polo button down since March 8, 1982.
