I just got my Barton Perreira gunmetal earharts and I have never been more happy with something I bought online. They're absolutely perfect.
If you are looking for something similar with a MUCH better lens look into Maui Jim. Polarized glass lenses will give you clear vision and reduce glare. I dont know how much the sunglasses above go for, but Maui Jim has a good bang for the buck. Great lenses and they have a great warranty.
I tried the Maui Jims at Nordstrom's and I like these much better. Plus they were $50 cheaper. I don't know much about lenses but I know these are polarized.
I think they're fine, they're pretty obviously masculine shaped. The Tom Ford I posted on the previous page I think would work if i dressed a little more rock star, but I'm pretty plain as it is so I think they'd come off femme
As long as you sport a faux hawk and wear a fluro one-size-too-small deep v, TR jeans and a pair of square toed 'snake skin' loafers, last thing you'd want is to look incongruent. edit: popped collar polo can replace deep v, or you could wear it underneath for that extra 'kick'
