well it depends which women you are talking about - the Uzbek women do tend to dress formally, which is largely quite modest. Russian women here, however dress slutty to the extreme. I swear I have seen women's underware because their skirts are so short/non-existant. It is odd to walk around the streets here - there is a huge contrast between the whorish euro-looking women and the formal and fairly modest Uzbek women. I think my slightly booby t-shirt was very much in the middle ground.

That said, hijab here is a choice that some women make, but most women just dress nicely and modestly.
