Clothes shopping in Dubai

All my shopping so far has been for food and the villa, I haven't purchased any clothes since we moved here. Today I went out looking for undershirts for Larry. First off, some stores don't carry them or they have 1 choice and not the right size. When I did find them the price was crazy, 195Dhs for one at the first store and then 349Dhs at the second. 195 is about $50US... who pays that much for a stinking undershirt! I miss Marshals... I need a shopping trip to the US.
