Even on a close to 100 degree day natural fabrics rule. Grabbed my old Garnet Flannel (summer flannel) HSM Hart Schaeffner and Marx navy blazer. I’ve recently bought some clothes from my buddy Steve Giles: light weight tan Gaberdine trousers (double front deep pleats) and a madras’s shirt (New England Shirt Company) and a silk navy with polka dotted pocket square. I added Pendleton socks, Martin Dingman bridle loafers and matching belt picked up from Travers Mahan Clothing and my old Wenger field watch with a navy/Green nato stripe band. Doesn’t get much more basic classic timeless menswear than this but still seems to fit the need. https://stevengilesclothing.com https://traversmahanapparel.com
