What do I notice about Rarity? Hmm…
She’s awesome.
I also notice that she’s unusually strong for a Unicorn. She clearly has training in at least two different fighting styles, and could probably kick the flank of anypony who challenged her… except AJ.
I really wonder how she’s able to stay in business. There’s a reason high fashion stays in the big cities, and trying to sell high-end dresses in a tiny backwater like Ponyville is a good way to go broke quickly. Sure, she may get the occasional out-of-town client and mail-order (see Sapphire Shores), but that can’t be enough to sustain her, especially not when she goes to a spa every week and gets The Works.
Now I’ve come up with my own answers but that’s headcanon territory and this isn’t the proper thread.
