A bold, no-nonsense black tee that speaks with dry humor. The front features distressed white lettering that reads: “Dumb people just don’t know they’re dumb,” laid out in stacked type that feels like vintage signage. Wear it when you want to shrug at nonsense, spark a knowing laugh, or break awkwardness with a blunt punchline. The shirt drapes in a relaxed, classic fit and the crew neck keeps the silhouette tidy while the roomy cut stays comfortable whether you’re out with friends or lounging at home. It’s the kind of shirt someone with a sarcastic streak reaches for when they want their mood — equal parts amused and unbothered — to be clearly stated.
