Length: 76.5 cm Width: 56 cm Size: 2 This should be a good size for someone around 170 cm tall. This shirt has a double-layered collar design. It also comes with a strap, allowing for various ways to wear it. I purchased it for around 50,000 yen during the 17ss season. I've worn it a few times, and the collar was a little dirty, but it has been cleaned. The condition is good, and I don't think it's noticeable.
