new vests are easily done.. you just need to make the textures and add some lines to the ini files for each of them.
more uniforms aren't hard either.. you can check my nightops uniform mod and look at the files in the archive to make your own if you like.
i was thinking about adding most of the clothing npcs are wearing as new uniforms as well.. to give the player more of a choice about looks... this wouldn't be very hard to do either... the only problem is that vests won't be visible when wearing these.. and to change that might require some additional coding done by r@s and lots of textures beeing made.... as each vest has a skin for the whole body.... it would require duplicating each skin several times and copy pasting the vests from the default skins.
this could be done considerably fast, as i have already made new versions of each of the default clothes for my nightops reskin mod and thus have each of the vests on a seperated layer for both males and females...
sometimes the texture layout is very different from the default skins and they have to be resized...
for clothing that shows skin the whole thing gets much more complicated.. as again you'd need to make new skins for every skin color.
all in all it would be a considerable amount of work and increase the size of the mod quite a bit.
in case you missed my mods and wonder what i'm talking about, here's a link to my thread so you can check out how i did it.

(note that the hotpants reskin is
not wearable clothing, i changed the default skin of these npcs to my custom skin...)
