Leggings do not “sexualize” a woman’s body (or, in this case, teen girls’ bodies) any more than a black turtleneck does. They outline the shape of a woman’s legs, which should not be shocking to anyone who knows what legs are. Are they appropriate for the office? That depends on the dress code. Are they appropriate for people wanting to take advantage of an exclusive work perk that comes with its own set of use guidelines? That also depends on the dress code. But they are common fare in public spaces, like airports and many schools, across divisions of age, size, gender expression, and economic bracket. When the public perception of a brand is that they believe leggings are inappropriate (never mind the fact that United attempted to walk things back by stating that leggings are welcome on all paying customers), it’s basically saying that they think leggings are offensive to other passengers and a public nuisance.
