Since you are young, and Irish, I'll cut you some slack.
However, there is no woman on the planet who really digs the just got out of bed look unless she is sloppy herself and, well, sort of the kinda girl you don't want a long term relationship with. As you said, your look attracts different types. I, for one, prefer ones who are smokin' hot, clean, have some income and I am pretty sure don't sleep with every band that plays at the bar. I also prefer girls with a minimum of Tattoos and piercings who know that its "supposedly" not "supposably."
All women judge you on your appearance. In order, the things they look at are:
1. Your shoes. Believe it or not, that is what they look at first. Have an expensive pair of old school, cool, suede Pumas? How about a cool pair of ostrich or faux ostrich boots? You are doing okay. Have a pair of Massimo sneaks from Target with Massimo written all over it? Already on the not so sure list.
2. Your shirt. The T-shirt should be either of a real, cool band, or something from a real, expensive store. The shirt have a cool design and say Armani A/X? Wow. Does it have the same exact look but have the name Kirkland Signature? How about that Hanson shirt you got at their last show. You are done. Look like Charley Sheen? Winning!


3. Your smile. If your mouth is full of brown, super crooked teeth, you are done. They don't have to be perfectly straight in the teeth, but they should be as white as you can get 'em.
4. Your smell. If you smell, and not in a good way. Done. If you have a pleasant smell, yum. Too much cologne? Done. Wearing the same cologne as every other "Jersey Shore" wanna be? Done. Covered in Axe, TAG, or other Body sprays? May as well just go home or be relegated to girls from Jackson, NJ.
I always tell people to cultivate a band look because of how it effects them musically. Having a look does have some other bennies as well. I find a neat, clean, body fitting T shirt, a pair of properly ripped jeans and either those cool Pumas or a cool biker boot not only has a great look on stage, but also works very, very well with the ladies....
My cologne? Well, I don't reveal that because I don't want every human in the world to smell like me. But it does cost over $200 a bottle, and, to paraphrase the young lady from a show last month, "What is it you are wearing? Oh my god, that is soooooo sexy man smell. MMMMMMMMMMMM"
