[Miss Bingley:] "Oh! certainly," cried his faithful assistant, "no [woman] can be really esteemed accomplished who does not greatly surpass what is usually met with. A woman must have a thorough knowledge of music, singing, drawing, dancing, and the modern languages, to deserve the word; and besides all this, she must possess a certain something in her air and manner of walking, the tone of her voice, her address and expressions, or the word will be but half-deserved."
Here's a good look at some of the expectations for upper class women: music, singing, drawing, a nice voice, and a graceful walk. Notice anything missing? Oh yeah: any skills or accomplishments that aren't purely decorative. No calculus. No economy. No critical thinking. Only things that will help her attract a dude.

"Elizabeth Bennet," said Miss Bingley, when the door was closed on her, "is one of those young ladies who seek to recommend themselves to the other sex by undervaluing their own; and with many men, I dare say, it succeeds. But, in my opinion, it is a paltry device, a very mean art."
"Undoubtedly," replied Darcy, to whom this remark was chiefly addressed, "there is a meanness in all the arts which ladies sometimes condescend to employ for captivation. Whatever bears affinity to cunning is despicable." (8.56-57)
Miss Bingley thinks being sooooo smooth when she hits on Mr. Darcy, but he sees right through her. We're not sure if she gets it, though, since she keeps on trying.
