This item was received around 1998-1999. At the time, I was 179cm tall and weighed 70kg, and this shirt was a loose fit, so I didn't wear it much. I've gained 10kg and grown into an XL size, and with the current trend of oversized silhouettes, I've had the opportunity to wear it in the last year or two, but my fashion tastes have changed, so I'm selling it. Please refer to the photos for the official size. The material is 100% cotton twill. It's a casual shirt. It doesn't seem to have any noticeable flaws at first glance, but there may be some changes due to aging, so I'll mark it as "slightly damaged or dirty." It's a used item, after all (it's a quarter of a century old, so it's in the vintage category). Please purchase with understanding. #Polo #RalphLauren
