Formula one mogul Flavio Briatore has linked up with designer Angelo Galasso to launch a luxurious clothing line for men. The pair aren’t playing around. The exclusive brand is called Billionaire Couture and apparently it’s exclusively for billionaires. One line item worth mentioning would be their black, water resistant crocodile umbrella. Why mention an umbrella? Because it’s the world’s most expensive umbrella at $50,000. The umbrella is available by special order from the Billionaire Couture flagship boutique on Sloane Street, London. We figure London is as fitting a place as any to buy a $50,000 umbrella, at least it will get good use. Check out the rest of the Billionaire Couture line, that is, if you can afford it.
