Thank you for viewing. This is a stylish gray men's vest from Tokyo Shirts BRICK HOUSE. The front is made of gray knit (50% wool, 50% acrylic), and the back is made of brown satin-like fabric (60% polyester, 40% composite fiber). This provides warmth, stretch, and breathability. Wearing it under a suit jacket will keep you warm while looking stylish! It's easy to match with various dark suit colors, so it's a must-have! If it doesn't sell by November 30th (Sunday), I plan to take it to a recycling shop, so if you've been interested, don't miss this opportunity!
