Emma Frost is one of the X-Men who is the least shy about showing off her body, which she actually considers as one of her greatest weapons. In Classic X-Men #34 by Marvel Comics, Frost revealed that she believes her risqué costumes are her battle armor, as she dresses to go to war each time she puts it on. Additionally, Frost said her looks and body were "on par" with any man's fists - which combined with her powers, makes her extremely dangerous.
Emma Frost is the White Queen, who immediately captured the attention of Marvel Comics readers with her incredible beauty and powers. Frost has never been shy ing her body and lingerie-like costumes to her personal gain to compliment her telepathic abilities and diamond powers. Her confidence in her appearance has gotten her out of many dangerous situations, including times she's shown off her body to draw her opponent's attention while using her powers to take them down. Frost's mindset about her body being one of her greatest weapons was never clearer than when she revealed to a fellow mutant why she wears sexy costumes and goes out of her way to show off her figure.
In the story Double Negative from Classic X-Men #34 by Ann Nocenti and John Bolton, an unnamed servant for the Hellfire Club dressed in a risqué outfit comes to Emma Frost, telling the White Queen that she hates wearing the outfits and being "gaped at" by the Black King. However, when she asks Emma whether the job is worth it despite the obscene amount of money and if the whole thing is sexist, Frost reveals her philosophy behind her ensemble - as she considers it one of her greatest weapons.
Frost tells the servant that when she wears the costume, it cheapens the men, not her. She says since the Hellfire Club is all about success and world domination, she's found a way to personally dominate using her appearance. She refers to her clothes as her "battle armor" and says she dresses "to go to war." In a strong statement, Frost reveals her looks and body are "weapons on the par with a man's fists," and she's always up for a battle. The White Queen also its there's no such thing as sexism unless you give them that power.
Emma Frost has never been shy about showing off her body with a series of revealing costumes over the years, but it's not just because she just wants to look good - although, that's definitely part of it. She knows she can use her body to get what she wants and command respect, as her combination of beauty and telepathic and other mutant powers make her one of the most intimidating mutants in the X-Men. She often uses her confidence and abilities to gain more power. Ultimately, Frost knows her body is a valuable weapon and that she can use it to her advantage. Nobody ever said Emma Frost wasn't confident.
