The preppy WASP in me thought my son needed a blue blazer with gold buttons for his 18th birthday but my skater-style son was not having it. This is mint NWOT from 2019, in a “modern fit” Nautica still sells for men for $295. It’s got the classic notched lapel, two-button closure, and four-button cuffs, with two front flap pockets and a left chest welt pocket. Navy “stretch performance fabric” is a blend of polyester, rayon, and wool, while the cobalt lining is silky polyester. Side vents and a nautical stripe inside complete the picture of this timeless staple of the preppy wardrobe. Boys’ 18R is like a Men’s S. Measurements provided on request.
