I think they’re a bit overused with some of the other suits. There are the standard leather gloves (without holes in the back) and I think they’d be considered more of a classic Hitman™ look.
Regarding suits with gloves… Those were typically rewards for killing ETs. You were essentially getting a pair of gloves. 
But when paired with a suit it makes it look like you’re getting “more”.
Birthday Suit with Gloves. 
Maybe someday we’ll have full suit customization. I can even envision scenarios where 47 would infiltrate (say) a restricted wing in a mansion where a lavish party is taking place. You could then choose to put on gloves to avoid leaving finger prints on a door you’ll be lockpicking, to get to a safe… etc.
But if you came to the party wearing gloves you’d stand out… But maybe that’s getting too technical and role-play’y.
