A night at the pub should be your chance to relax, with your friends and a cold beer, so make sure what you wear suits this aesthetic, this isn't the time for suits and ties, but that doesn't mean you can't dress well!
A plaid shirt, like ours from Portuguese Flannel is perfect, team this with a pair of black tapered denim jeans like these 12oz ones from natural selection. For footwear, try a pair premium Ludwig Reiter trainers, made in Vienna from supremely supple calf skin suede. The selvedge cotton denim overshirt from French workwear brand Vetra works brilliantly as a stylish lightweight top layer.
Finish the look off with accessories from Triwa, a good watch (so you're not too late home). And a pair of sunglasses, for venturing into the pub garden, all with feature flattering frames and Carl Zeiss lenses.
