That's kind of the point of the character's journey in the film from what the trailers suggest. That he tries to take over Wakanda and rule it. Which in the MCU as set up by the comic lore, the panther suit is the symbol of Wakanda and the Royalty itself. So story-wise, to take over the nation, would be to adopt the mantle/suit too as the symbol of the ruler of the country. Same reason Shuri became the Panther when she took over as Queen of Wakanda in the comics. (And in the comics, that's exactly what Killmonger did too with taking over the mantle of the Panther when he thought he had successfully killed T'Challa. Though I do wonder if they'll connect Killmonger to the still active Ten Rings the real Mandarin heads up.)

The MCU version is a little different than the comic version but overall this is still an exiled former Wakandan coming back to try and usurp the throne. They've made some other minor changes to T'Challa as well by making Wakanda more isolationist than the comic version. The comic version accidentally diluted some of the premise by adding in how T'Challa went away for school and some other little things like that. This versions is a more isolationist nation that built itself up from no interference from the outside world, developing into far more advanced technology than even Tony Stark can dream of. It's being made more cohesive way to maintain the story integrity of what Wakanda represents.

In Iron Monger's case, it was because the suit was directly reverse engineered from the Mark I and to show how unoriginal by comparison the villain(Stane) was. It represented idea theft and reverse engineering. Which is why in IM2, we see Whiplash mock corporate unoriginality. He was creative and came up with his own gear and ways to tweak the Hammer drone designs. Which was the whole reason he was hired, because of corporate unoriginality not being able to match Tony Stark's level.
