Looks like the skinny-jean version of a suit, to me, and I think I have seen that on some very athletic and/or thin celebrities and/or movie characters in costume. And maybe that’s caused some people to want to look like that or worse, or some suit marketers to want to try to sell that.
Though looking for an example, I’m not finding a celebrity example that’s as bad as @ARE_you_kidding_me ‘s article examples. One I was thinking of was Derek Hough (who is a very fit and thin dancer) but it’s not bad like that – he’s just thin and his suits are sort of tight – but I can imagine them inspiring guys with body obsessions (of which there are many) into wanting to get tight suits when they shop for themselves.
