100% certified layering baddie. This shacket is giving heritage uniform energy with a Sundae School twist. The corded cotton twill has that sturdy, structured fit, but it's not stiff or crusty. She drapes. The shawl collar keeps it classy while the relaxed fit keeps it nonchalant. It’s tailored enough to look intentional, oversized enough to feel effortless. Throw it over a tee, layer it with a hoodie, or button it all the way up for that clean minimalist vibe.
