First off dude, what are doing looking like you are going golfing while you are out picking up women? Obviously, there is more to game than just clothes, but there is a time and place for that look. It can work well with women in certain circumstances, like at the country club maybe, but if you're really gonna clean up out there you gotta experiment with your style. That doesn't mean you have to be inauthentic and get tattoos and wear leather jackets. But take some risks and put together some slick outfits for varied venues and circumstances. Put a touch of sexuality to them and you are off to a good start here.
The truth is, the more you understand a women's niche in the world the more leverage you have in seducing her. If you really want to seduce edgy women (or classy, or creative, or whatever type) You're best to find ways of being that type of guy yourself. Especially for a long-term relationship. If "changing" yourself feels inauthentic, well maybe just attract women more in your wheelhouse. This being said women will often get with a guy who she says is "not my type." Especially for hooks ups. Especially if he is a skilled seducer with a strong lover frame.
Edgy women (or any woman for that matter) are just people. If you are running your interactions based solely on appearances you will only get so far. Devople the ability to read deep between the lines and you are off to a good start. You are aiming for her humanity. Her biology. Not her cannibal corpse t-shirt, and her skateboard. Here are just a few ways you can use the differences you two have to your advantage
-build rapport by highlighting something universal about her interests. Then use that as a springboard to deep dive. Like if she like metal music and you like classical don't try to get on the same page about your musical taste, instead focus on something like how exciting it is to see your favorite musician live for the first time. Or how music can be such a time capsule for certain periods of our life. This of course works best when you have built a little rapport already.
-Playfully tease about your differences to build a bit of tension and fun. "I'm not sure I could ever fall asleep next to you, too worried I'd wake up with a tattoo" "You're aware there are no mosh pits at the country club right?" "If you behave a bit more I might let you crash my golf cart"
-Use your differences as an opportunity to teach each other about your interests. This works especially well for seduction when you assume the teacher role. If you already have framed some of your disparate interests as something more universal you can entice her into your world. I mean if golfing is all about being present with the moment, just like skateboarding (which she is all about), she might want to "swing your club around" (especially if you have set a sexual frame to the whole endeavor). Also, if you get her to teach you about aspects of her world, it gives her an opportunity to share a part of herself.
Let's be clear here though. Seducing women is already a bit of an edgy thing to do. And if you are good at setting a sexual tone with a strong lover frame, you already have the edge. Approach with confidence. Keep things simple, and don't see your differences as a barrier. See them as an opportunity to create a novel and adventurous new connection.
The best way to gain experience approaching these types of women is to get out there and go for it. Just take the leap. I will say this much about them though. From my experience, edgy women use that edginess as a bit of a front. If you are able to see that edginess as a bit of a playful front and call them on it, they usually melt. Just expect a few sassy bad girl type shit tests thrown into the mix from time to time.
