I was trying to think if there were any characters who had costumes in this style who were still wearing them after 1989 or so, the best I could come up with was Nova, who I think kind of fits here?

Nightcrawler still wore those disco shoulder pads and V-cut in the 00s, though I guess with him they were kinda justified by his "swashbuckler" persona.
