Question: Biker Gang Member Outfit G8M (or G3M) - what clothes could be used?

The title already says what I look for, but I give some more details.
A short while ago I got me the Old Chap figure, partially because seeing that promo picture of him riding a motorbike gave me a couple ideas.
I already found some nice bikes I could use, but finding a proper Biker Gang Outfit for a G8 male seems a real problem for someone with little knowledge in DAZ and none whatsoever in Hexagon/Blender/etc. So I would need some clothes, which would be easily adaptable by using some built-in resize morphs and Gimp for diddling around with the textures.
What I look for:
- either a jeans/denim vest OR a leather vest. They should be going down right to the trousers' belt. opened/closed morphs are needed. Supposed to be worn above the jacket, so a resize morph is needed, too.
- either a leather motorbike jacket OR a jeans/denim jacket. They also should be going down to the trousers' belt in length. Opened/closed morphs needed here, too.
- if possible both of these for a G8M. Or, if not possible, for G3M. I'm not sure if my skills are good enough to manage to fit anything before G3 to my figure...
Optional: a beltbuckle for the trousers in form of a skull
What I've found sofar:
Ugly Dave Outfit (https://www.daz3d.com/ugly-dave-outfit-for-genesis-3-male-s) looks great at first glance, but has the buttons on the wrong side of the vest. No selfrespecting biker would wear a girls vest. Nice beltbuckle, though, which could possibly be transformed into a skull somehow...
Everyday Casual Outfit (https://www.daz3d.com/everyday-casual-outfit-for-genesis-3-male-s) which also looks nice on first glance, but shares the problem with Ugly Dave's - buttons on the wrong side...
Hoodie Outfit (https://www.daz3d.com/hoodie-outfit-for-genesis-3-male-s) which is also nice, but just looks like a jeans/denim vest, but is a hoodie jacket instead. Might work, but having to either find a way to crop out all the not needed parts or turning them invisible, so that it could be worn above a leather jacket is probably beyond my abilities.
Leather Jacket for Genesis (https://www.daz3d.com/leather-jacket-for-genesis) looks rather unspectacular, but could do the job... though a jacket with more buckles and stuff would look more proper...
The Leather Jacket (Renderos... partially NSFW) has exactly the look that I'm after. It's for G3 females though, so I'm not sure how it would work out being put on a G8 male (or when he's with his friends, even several G8 males of different body proportions..)
Questions:
Considering the problem with the buttons (see above): might it be a texture problem only? So that just using GIMP to change the texture, that it shows the buttons on the other side might solve it?
Could just making the sleeves and the hoodie of the hoodie jacket invisible be a solution so it could be used above a leather jacket after a bit of a resize?
And a short explanation about the vest/jacket combinations I look for:
To me as an outsider it seems, that most Biker "Clubs" (or rather Gangs) seem to use either a jeans/denim vest over a motorbike jacket or a leather vest, made from a motorbike jacket over a jeans/denim jacket (or sometimes just over a shirt/t-shirt/hoodie, like in some TV show that ran a couple years ago...)
So if I don't find what I'm looking for, probably the Hoodie set might be the easiest solution, though it's just not "old style" enough for a guy like the Old Chap, who started riding a bike way before hoodies were even a thing...
Thanks for any help You are willing to offer
