Emma Frost is particularly notorious for this sort of outfit. As the White Queen, it was required attire for female members of the Hellfire Club, but she actually seemed to enjoy it, as it symbolized the power she could exert over men, using it for psychological warfare. (Not to mention that she admittedly does it for attention. Even after her Heel–Face Turn, she has worn outfits that have shown a lot of skin.
During her time with the Phoenix Force, she ends up more covered than her usual outfit, if arguably more risque. But her fellow Phoenix-er Namor somehow contrived to look like a male stripper. note Keep in mind that Namor's "classic" outfit is just a green speedo. And his modern outfit is also designed to draw attention to his bare chest and (sometimes-bare) arms.
The Invisible Woman of Fantastic Four fame is notable for being one of the relatively few comic book super-women who manages to avoid this trope, wearing for the most-part the same largely practical blue jumpsuit also worn by the male members of the team; however, Tom Defalco's run on the strip during The Dark Age of Comic Books was notable for reverting to trope and putting Sue in another, more revealing outfit. Which, by the way, she still wore while she was in mourning after her husband Reed Richards' Comic Book Death.
There is one example of a (parody) female superhero that doesn't go for the skimpy outfits while on the job, despite her day job being a supermodel: Ashley Crawford of the Great Lakes Avengers. Then again, as a hero she's the super-strong, super-tough, super-fat Big Bertha. Seeing her in the skimpier Emma Frost uniform is likely not what the average comic fan is looking for. Of the remaining girls on the team, Squirrel Girl has a more modest costume setup (she's still a minor), while Tippy-Toe wears just a ribbon. And is a true squirrel, so it doesn't count.
Whiplash/Blacklash from Iron Man. His Blacklash costume frankly makes him look like a prostitute, being an entirely leather ensemble featuring lots of studs and a gimp mask! In all probability, the character himself didn't realize what that look implied, but his successors, a husband and wife who took on both the Whiplash and Blacklash identities, revelled in it.
Captain America wears Nomad, which sports a Deep-plunging neckline exposing his chest and abs.
Carol Danvers of Ms. Marvel fame used to be one of the poster girls for this until she went all Captain Marvel and started wearing an all body covering suit. The next two Ms. Marvels both lampshaded and cracked jokes on Carol's fashion choices: Karla Sofen (the villainess Moonstone, who wore the original black, blue and red suit as part of the Dark Avengers) complained about it◊, and Kamala Khan (who after getting powers somehow got the black and yellow version) described the leotard as a "politically incorrect costume" and regretted wearing it because it gave an "epic wedgie".
The female Runaways are mostly an inversion, since they fight in civilian clothing and are supposed to be underage.
She-Hulk sometimes plays with this in her comics, especially the series where she spends more time on the Fourth Wall. In one memorable scene Venom randomly breaks in to the courtroom (she's a lawyer) and webs her up, and in ripping the webbing, she rips her suit. Someone notes the readers have just gotten more interested, wondering if it's a popular villain or the ripped clothing that excited them.
A male example is the Sub-Mariner, a superhero whose most common "uniform" consists of basically a speedo and wristbands.
The Ultimate Marvel version of the Hulk, who is gray, not green, was originally depicted as wearing nothing at all! No ripped purple pants for that guy.
Considering that she's gone through well over a hundred costumes since she was created, Wasp has surprisingly few of these, sticking mostly to bodysuits that cover most of her from the neck down. The low-neckline ones or sleeveless ones are actually notable.
While most of the female X-Men fall victim here (even Jean Grey bares her midriff in the X-Men Legends games), Rogue averts this out of necessity. Which somehow doesn't stop her from dressing like Daisy Duke when she's out of uniform. The younger X-Woman Dust is a full-time inversion, being a devout Muslim.
Psylocke in particular was (in)famous for her purple thong leotard which she wore from the 90s to the early 2010s.
X-23 (Laura Kinney) wears many different revealing outfits, including a fanservice-y school uniform.
Dagger of Cloak and Dagger has a skintight white bodysuit with a dagger-shaped cutout in the front that had a physically impossible open area over her breasts that still concealed (somehow) the crucial spots, and extended down below her navel.
◊, and Kamala Khan (who after getting powers somehow got the black and yellow version) described the leotard as a "politically incorrect costume" and regretted wearing it because it gave an "epic wedgie".
