I'm guessing that if the petticoat is seperate you can re-use it with a different skirt/dress....
As for does it have to be the same brand? I don't know, I just use whatever I want from whichever stores tbh.
And depends on the style of the pettipant or the skirt/dress. But I think most of them would look okay with either.
Unfortunatly I haven't brought anything from those two websites so i can't help you there.
