my personal preference with "emo guys" is dark wash skinny jeans, a Glamour Kills t shirt, metal/post hardcore band t shirt, flannel/plaid shirt, or hoodie, and converse, osris, or etnies! and I absolutely LOVE gages too! good luck! I hope my advice helped. ^.^
Unless you're under the age of sixteen, "emo" isn't going to impress anyone. You'll just end up looking immature (except to very young or immature girls) - and maybe you are, because it seems that you're just trying to get girls. Also, the girls of the alternative scene will probably call your bluff - especially if you label every alternative style as "emo." Ignorance is a dead giveaway. In fact, doing that will not only reveal the false image for what it is, but it will also annoy whatever girls you're trying to impress.
Be yourself, and girls WILL be impressed. Go whatever style you think suits you best - whether it's "emo" or something else.
For emo eyes seek out the forgotten, shy girl in the corner. For emo ears, listen to classic emotive hardcore. For emo lips, speak words of...haha okay, so I think Audrey Hepburn already did this (re: Audrey Hepburns Beauty Tips - Google it).
Basically, confidence is the best style accessory a guy can have (not up-himself-ness), especially emo guys, as you will break the typical emo stereotype by having confidence. Also, studded belts and slightly skinny jeans are vey cute ;)
