Oh. Nothing's wrong with it. Not if you're working on a farm. That is what is expected of you there and even I can see the reasons by wearing something so... unrefined.

[You will never catch Rarity in a pair for jeans. Except on nightmare night. That was the only exception.]

In a clothing shop, it looks extremely unprofessional to wear something like that. So, I'm sorry Applejack, but if you want this job, then you can't go in dressing like the Clamponies. Jethro and Ellie Mare don't really appeal to the higher class customers.
