As a tourist, it is important to dress conservatively while in Dubai. Although Dubai is more cosmopolitan and modern than most other cities in the Middle East, Muslim values are strongly enforced here as well. Women in particular need to dress modestly. When selecting clothes, pick clothes which are lightweight, loose and flowy. The hot climate all so requires one to wear clothes that are comfortable and allows your skin to breathe. Pick soft natural fabrics such as cotton. Avoid any garment that is tight, sleeveless, falls below the knees, and with plunging necklines. Arms and legs should be covered well. A headscarf will also be useful if you are visiting a place of religious worship. Long dresses, skirts below the knees, kaftans, loose shirts, t-shirts, short-sleeved tops, harem pants and lines trousers are a good bet. A few nice dresses should suffice when going out for dinner at restaurants in Dubai. When it comes to footwear, opt for light sandals and good walkable shoes, especially if you intend on visiting the desert.
While in your hotel, of course, one can wear clothes more freely. Hotels such as Avani Deira Dubai Hotel are among the choices to consider when looking out for accommodation options. On private beaches, such as in resorts and hotels tourists can wear swimsuits and bikinis. However, if visiting public beaches, locals dress modestly such a piece and sarong for added coverage.
If travelling during the winter, the nights can get chilly. So, pack a few sweaters and a lightweight jacket.
