It's just like real life - you can wear your sweatpants in your college classes but you'll need to buy some khakis for that internship - and when you want to go out for that job interview in DC you'll need a suit - and then when you own the company you can show up in sweatpants and not a goddamn person can say a thing!
In any case, you have to wear pants you already have to go to the store in order to buy better pants.
