The women in Dubai dress like every other woman, but in a moderate way, they do not fancy revealing clothes, because their religion does not permit cloths with opening or tight skimpy dresses.
There are strict rules on how to dress in Dubai, and this applies to everyone, both foreigners and locals. These rules are, they do not allow explosive wears like bum shorts, short dress, and other skimpy wears.
You are not allowed to wear clothes with provocative slogans, and the locals all cover their hair; however, this is not compulsory for a foreigner as it is their (the Locals) culture.
Most people get scared away because of this; however, Dubai is a fun place and a welcoming place for everyone.
