Ecuador shopping- whats the situation with bra?

Does anyone know if there are brand stores in Ecuador? Would that be possible to find say Tommy Hilfiger clothing or Calvin Klein? Also what's the situation with perfume stores? I'm thinking to leave some of my newly purchased perfumes here to a relative as I've already got loads of stuff to take with me and she's really asking for it. But I'm wondering if I will be able to buy these same perfumes later (its mostly Lancome and Chanel brand) in Ecuador? Or should I get them somewhere in the duty free zone at the airport?
