ZUMURUD in Villagio is really gorgeous. But the good ones are always out of stock. It's not very cheap, the plain abayas can go for 400QR at the very very least, the ones with minimal emroidery/sequin things can go for nothing less than 700. Mine had orange crystal things lining the edges and it was 850QR. You can poke around Souq Aldira which is a LOT cheaper, but the quality is mediocre at best.
