This is an "Ascot Charpa," a hidden gem from Atto Vannucci / アットヴァンヌッチ. The Charpa is essentially a scarf, and the Ascot is an Ascot tie, combining the best features of both. It retails for around 30,000 yen. It's been worn a few times, so there's a little wear and tear, but I think it's in good condition. You can simply wrap it around your neck with a shirt, polo knit, or skipper for everyday wear! It gives a very stylish impression.
