Tortoise shell is the coolest. It changes depending on light, it's classy but dressed down at the same time. It's timeless. These don't feel super strong, so you'll have to to good care of them (they wont survive a sit-on situation), but in every other regard these are fantastic. We loved the way the arms snap into position and the gold/tortoise combo is enough to make you go all weak at the knees. Lens are crystal clear and perfectly round. They fit a touch smaller than some other pairs of glasses - like the clubmasters on the site, but the arms are flexible enough for anyone to wear them.
