Don't know if it helps, but Decathlon have a very interesting range of sunglasses for around 20 euros I think ; one of my mate bought a pair an is genuinely enthusiastic about these, might worth having a look if you have access to one nearby (we have lot down here in France)!
Do the stripes on the arms make these look like fake Gucci?
I'm after a spare pair of cheapo glasses, and like these, but don't want people to think they're Gucci or a fake pair of Gucci glasses.
Cheers.
