There is definitely a fuckboy uniform LOL.
But, I dunno. IMO your style signifies who you are and how you portray yourself to the world. You can't really see Donald Trump in skinny jeans put he pulled mad pussy for like the last 50 years.
Also I think the concept of
tribes are important. The beauty of the fuckboy fashion is most girls could rationalize hooking up with a fuckboy no strings attached.
I do really well with professionals in a suit. (The problem is there aren't many in where I live.) I did much worse in a hippie attire. I did very well with lame college chicks in a hippie attire but professionals scoffed me.

Being from the same tribe always helps massively with comfort. It also helps with her rationalize shit to herself (you don't need to hijack her emotions as much) and for more easy long term situations. You're from the same tribe, it just makes sense for you guys to be together, you know? Logically and emotionally/subconsciously.
Or... You should be in a tribe she wants to visit.
Now for some women it could be the fuckboy tribe. For some women, if they want the man in charge / they're ambitious, it could be the corporate tribe. Etc.
But as Neil Strauss put it YEARS AGO:
You want to portray yourself as either a member of the tribe she's in, or the member of the tribe she wants to be in or visit.
The women that want to visit the fuckboy tribe tend to be... Well... Fuckable.
So dressing like a fuckboy acts like a screening mechanism.
But... IMO...
You should dress like something
congruent to you that has a part of you
but also you should dress in a way of someone in your head who gets laid. Using your dress as a
Commitment and Consistency Principle for yourself has incredible results in real life. But if you make it completely incongruent you either have to fully change your identity to that or you'll have a massive split identity / imposter syndrome kinda situation.
Lean into your core personality but push it in a direction.

For example,
I run corporate businesses right? There is no fucking way I'm gonna wear Air Force 1's with distressed jeans when I go out into the business district LOL.
But instead of wearing a boring classic black loafer, I can weak shiny Gucci loafers, or a white classic loafer or a green croc leather loafer, etc.
I'm gonna wear a shirt and a blazer but I don't have to wear a Comfort Fit blazer but a better fitting one. With a color that's dashing and cool in my head and congruent to getting laid. I'm gonna wear a pocket square. I can wear a boring blue polka one or a striking silk red one. The shirt could be Italian cut/collar. Well tailored. Absolutely rocking. 2 buttons open. You see where I'm going with this, my man?
That's my litmus test. Can I see myself getting laid in this? Do I see someone getting laid in this. I buy dark red, dark grey and metallic blue shirts because they look PIMP AS FUCK and I feel my swagger in them. They propel and push me to act in a certain way. But a light blue? Meh. I can close clients in it but too business.
So my point is this, you can make anything kinda pimp. There is definitely a fuckboy uniform but if you are a business owner in a serious field that uniform would make zero sense on you.

Some classic uniform like outfits:
1) Good shoes, Jeans, Tshirt. (+Thick layer, blazer/bomberjacket/leather jacket/overcoat/etc.) (Most PUAs dress like this LOL.)
2) Good shoes, Jeans, Shirt (Old Rsd max, old Tyler)
3) Good shoes, Jeans, Tshirt/Wifebeater, Shirt as the layer (Rsd Tyler dresses like this.)
4) Good shoes, pimp slacks/chinos, tshirt/shirt/turtleneck, Top layer. (check out G-Eazy.)
5) Just a pimp ass suit. You gotta absolutely own it though and the environment has to make sense. (check out Micheal Sartain)
6) Casual shoes / boots, skinny-distressed jeans/sweatpants, oversized tee or a hip shit/hoodie, etc., a street jacket (could be leather or a bomber or one of those hip technical things.)
Honestly my uniform is Wingtips, Jeans, Crew neck Tshirt/Shirt/Sweater, Blazer/Overcoat. It's pretty business casual and it makes me comfortable and congruent in both areas to operate like that.
Because not everything is about pickup or girls for me. You gotta conduct yourself in a way that also makes sense for the rest of your life. I. M. O.
