I know he's (rightfully) looked down on now because of how he is IRL, but one of the things people praised about Joss Whedon's Astonishing X-Men run is that it got rid of the Quitely/Morrison suits and put the X-Men back in more traditional superhero attire. That Astonishing X-Men run in general was actually pretty good, it introduced the "mutant cure" stuff that would be partially taken for X-Men 3, it introduced Abigail Brand (one of my favorite X-Men supporting characters) and even the variation on Wolverine's costume introduced in Astonishing has pretty much remained the basis for most of his costumes since then (even in Deadpool & Wolverine the Wolverine costume they use is basically the Astonishing suit with sleeves and "movie superhero costume" material).
