Can never go wrong with jeans but try to go for the more interesting kinds, different shades, bootcut, interesting stitching designs . . . also make sure the shoes look newish and cool. When they get messed up, time to buy some new kicks.
I always wear a T-Shirt under a shirt - never button the top few buttons on a shirt when wearing it this way. I tend to buy a pretty suave shirt, often long sleeved that I will just roll up or else buy one with long sleeves that fasten up already with a button, yeah . . . they make those.
Try not to wear more than three colours. There's interesting then there's a christmas tree gone wrong.
Jackets? I find some leather jackets can look good but you really need to spend a lot to get a nice one. Just go for some trendy light thing, s'all good - just no pull on hoodies, or anything pull on for that matter.
As far as hair styling goes . . . I used to wear my hair kinda long but got it cut real short with some length at the top to spike it up, I use styling wax - for a better hold, that lasts ;]
Girls seemed to respond to the change, I grew it long to attract a certain type of girl but found the hair length isn't part of the attraction when the cut only earned more attention.
You know you read a lot of the time, "shave well" . . . Sure, nothing wrong with a 'clean' fresh face but I've read some interesting articles. I am 19 and could grow a beard since I was like 16 with my Chuck Norris genes, thought it was a drag until recently I learned that a little stubble is a sure sign of sexuality in males, apparently the chicks dig it - moreso than that illusive six pack!
Finally, fragrance . . . we all know the good brands, they are the expensive ones you need to save for. For deoderant, I find Linx/Axe does some pretty alright fragrances.
Cologne-wise, I have started using 'Givenchy - Very Irresistible Fresh Attitude Cologne'. It is indeed a fresh delicious signature sent I would recommend, far better than all that fiery cheap stuff that stings the nostrils.
Accessories? I used to think chicks responded to a lot of bling bling and so I would wear massive silver chains round my neck and wrists that I would buy from T.V. sales. No, it just looks cheesy, immature and stupid having all that metal. Buy a nice watch, leather or metal and wear something interesting round your neck, not a shark tooth but even some surfer beads . . . just something to catch the eye or mention briefy.
Keep in mind you own the material, not the other way about.
It should NOT be . . . "Hey, Ben Sherman shirt, levis jeans and figaro chain here, could they introduce you to me . . . "
You own the clothes, you bring them to life. It should be the case of you mastering your own design and approaching the ladies feeling confident being DJ savvy and bold in your refreshingly stylish look.
Anyways, I just thought up a terrible chat up line I dare one of you to use . . .
"Hey, you know I used to be on the menu here until they took me off for being too tough, I tried out for a dessert but turns out I was too sweet . . . *hand over piece of paper with your number on it, or an empty piece for her to write her number* my luck, huh?"
Btw...it definately won't work in a book store.
