Sunglass model suggestions?

[Ossi O]

Hi, I'm looking for similar sunglasses as in the link below, just a bit higher quality(those cost some 20 dollars per dozen). The main requirement is that they're plain and simple, not all wavy etc. The sides and front part should also be of equal width. And if the sides don't curve but form an angle at the hinges(not present in the picture below), that would be even better. The colour doesn't really matter. I'm just looking for the right shape. Thanks a million for your suggestions!
