Although the skater type guys aren't the only type of guys I'm attracted to, I think for me the reason I find some of them appealing is because they're image is completely opposite of mine. I'm mainly a mix of the Express, The Gap, The Limited and Old Navy. "Skater" guys have that "I just rolled out of bed and threw on some baggy pants with some vintage t-shirt and a pair of Vans" look. It's hard to explain, but somehow they can still look presentable and pull it off and girls still are attracted to them. I also find the same appeal with guys that have a Gideon Yago look going. (he's on MTV for those who don't know who I'm talking about) There's just something about Gideon.
