"Do not make yourself uneasy, my dear cousin, about your apparel. Lady Catherine is far from requiring that elegance of dress in us which becomes herself and her daughter. I could advise you merely to put on whatever of your clothes is superior to the rest—there is no occasion for anything more. Lady Catherine will not think the worse of you for being simply dressed. She likes to have the distinction of rank preserved." (29.6)
We are so sure that Lizzy is comforted to know Lady Catherine won't mind her Jason Wu for Target dress. You wouldn't want everyone to be wandering around in Valentino, right?
Quote 11
"When I do myself the honour of speaking to you next on the subject, I shall hope to receive a more favourable answer than you have now given me; though I am far from accusing you of cruelty at present, because I know it to be the established custom of your sex to reject a man on the first application, and perhaps you have even now said as much to encourage my suit as would be consistent with the true delicacy of the female character."
"Really, Mr. Collins," cried Elizabeth with some warmth, "you puzzle me exceedingly. If what I have hitherto said can appear to you in the form of encouragement, I know not how to express my refusal in such a way as to convince you of its being one."
"You must give me leave to flatter myself, my dear cousin, that your refusal of my addresses is merely words of course." (20.16-18)
Mr. Collins is basically totally taking away Elizabeth's ability to speak or form opinions, and trying to get her to accept this proposal just by sheer force of not accepting her refusals over and over again. Could he be any creepier?
