But really, there are more Uniqlo stores here than in all of California. The island is the size of LA proper. There are like 20+ stores here! Also as a great side note-- you get GST and the prices are the same as LA (as in things that are sold for $49.90 in the US are $49.90 Singapore dollars-- sweet).
We spent a lot (too much) time in Isetan. What I personally can't deal with is salespeople who follow you. "Good service" here means that the lady will run around the shop and find you other things that you may like to try on and buy. Note: in Singapore, there is no return policy at most stores... You've been warned.
O.A.M.C-- these are dresses by a local designer. They're sold in Isetan (but if you can't find the things you want they do have their own store-- we found it in the mall that's connected to the Raffles City stop--aka citylink).
We've been told by one of my Aunties that we should look for Korean fashion clothing stores (there is one in the Jem mall). Stay tuned...
