the last pic is really sexy and classy, but seems a little to clean cut for me, the second to last is too... jersey shore, lol. The first pic seems a little young to me... not really a unique style.. but at least the shoes aren't those rainbow ones, lol... it's too sporty/hip hop for me.. I couldn't find anything that really matched what I like but this is sort of like it, link
I don't like anything that is too thought out... really laid back and natural like he's not trying to impress
link My man normally wears stuff like this, and lots of polos...but when he's at home or working out he will just wear wife beaters and sports shorts. I love his entire style, and I think he looks good in his polos lol.
Definitely something more like the last link or somewhere in-between the second and last, for casual wear... There are some "douchey" overtones to the look in the second link. It's not bad, could be worse, but it could look a lot better if done right and give off a better impression.
But go for something a little more classy/expensive looking... Totally attracts the right kind of attention.
