i've been to aida twice recently ... nothing is last seasons (this is the current season and some items on sale from past seasons ... like any other shops) and they had sales recently (up to 60%).
the people are really nice ... i don't know for women but for men they carry dior homme, balenciaga, alexander mcqueen, galliano, armani, les hommes, cdg, kris van assche, margiela and more i think (some cheapest things like Surface to Air).
for women they do balenciaga for sure (bags and outfits), they also carry chloé bags and luella and mccartney ...

and FYI : to enter the shop enter alfardan tower it's on your right.
