Does it make them a try hard or attention seekers. Is it sometimes a turn off when everyday he dress awesome not like a suit but really cool style that differ from everybody else. And does a keychain makes things cool.
No, it never occurs to me that stylish guys are "trying too hard". If that were true, ALL women would be trying too hard, haha!
It's great to have a good sense of style... but if I notice he doesn't want to walk for fearing of scuffing his shoes or doesn't want to sit on a bench in a park for fear of wrinkling his clothes or getting dirty, THEN I'd be turned off. I don't really like metrosexual guys, it's too much for my taste.
