A white T-shirt over an oversized short is the Justin Bieber summer staple, subsequently making it the Summer go-to for the rest of us. And as far as T-shirts go, this one is elite: 100% cotton and breathable. Pair it with these burnt orange shorts for a casual park-to-pub fit, and a sweater tied around the shoulders on the (likely) chance that you're out late.

The power of a crisp shirt to smarten up a casual outfit cannot be understated. Chosen correctly, it transforms an otherwise gym-only look to something that can be worn for dinner, drinks, or even a date.

The phrase "real men wear pink" is obsolete in 2026 because, well, we know. But if you did need any further convincing, this t-shirt paired with white barrel-leg trousers would do it.

Working out on a summer's day can be a sweaty affair, but Uniqlo's Dry-Ex T-shirt wicks moisture away from the skin and includes ventilating panels to increase air flow. Pair it with a parka for cooler late night or early morning runs, and dark sunglasses to swag up the fit.
