Are we still talking about characters for a fighting game?
A few perspectives you might want to approach it from or use for google searches.
Do you just want fashionable gloves or something more practical?
For fashion gloves, do you want elegance, or something edgy and out there?
It would depend on the character I suppose, so I'd be looking at basing it on gloves made to allow gripping, etc. Maybe something like grappling gloves, but without the padding.
I'm partial to driving gloves.
Fingerless and with openings at the knuckles may be better, but I quite like these too
This site has various gloves made for practical purposes
