How is that Kurt's dad can't afford paying for the private school (and has to spend honey moon savings), but can afford to buy Marc Jacobs or Burberry clothes for Kurt?

how should I know???

private school's alot more expensive than designer clothes, alot of people are at my school on scholorship because they'd never be able to afford it otherwise but they can easily afford designer clothing.

I would like to assume that Kurt probably shops at stores like Century 21 or stores that sell designer clothes at a cheaper price... or (I'm not sure if Kurt has a job but if he does here's my other explanation) Kurt saves up his own working money to pay for the clothes :)
