After months of looking, finally a common high-street shop is prepared to make and sell flares for men. And not just slightly boot-cut, either, but up there with the Pop Boutique flares and the like. I suppose you'll be wondering what shop this might be, and the answer is the Belgian-based chain-store C and A, so sorry to anybody in Britain, or in some other area without said chain, but you'll just have to travel abroad for these (or maybe you can order them over the Internet somehow....)
C and A are now selling flared hipsters for men (sadly not in my size), so maybe they've cottoned on that there's a market out there. Mind you, they're also selling convertible Kar****nhosen!
