Vintage Sag Harbor Black Single Breasted Button Blazer Gold Button 8 Oversized

Vintage Sag Harbor blazer in black with a gold knot-style button — classic notch lapel, single-button front, patch pockets, boxy 90s cut. This kind of softened, easy-fit blazer is exactly what’s driving the “librarian chic” tailoring trend for fall 2026, where blazers are worn oversized and layered rather than boxy-corporate. Linen-look without the wrinkles. Size 8. Fabric: 50% polyester, 50% rayon. Assembled in Dominican Republic. Condition: vintage, pre-owned, no flaws noted — please zoom photos and ask questions before buying. Wear it open over a turtleneck and trousers, or belted over a slip dress for an easy transitional layer.
