Years ago, I saw a comedian who did a thing about how, when you're carrying your shopping in a thin striped carrier bag, everyone knows you've bought something crap.
Not if you've got a leather version, though. This take by Natalie Thakur costs a whopping £140 from Not on the High Street, but it's a great idea and a durable bag. It's also available in blue and white.
