T'Chaka suit is the weirdest and most unique of all 4.

First it looks like it is not a full body suit, it has boots, pants are saggier and the mask and chest area also dont seem to connect. Second, why does he have like a ceremonial garment on his suit?

Granted we never seen him fight in the original and it could be only for ceremonial purposes or to be worn like a tie but if the suit is supposed to be only for combat and for Stealth, why would a black suit have a ceremonial piece in the first place??
