I mean, sometimes people need to try on clothes before they can be sure it will fit? Who exactly are you picturing here when you say "ditzy"?

You act like this is taking money out of others' wallet- imagine how much money shoppers would lose if they had no recourse when a product didn't perform as expected. It doesn't need to be broken to be disappointing, and returns are one of the few tools consumers have to protect themselves from companies that oversell and under-deliver.

There's a distinction between mis-selling (where returns are obviously legitimate) and being disappointed.
