Dubai Tower, the tallest building in the world.
"There is no specific dress code in Dubai, and you will see both ends of the spectrum from women who cover themselves from head to toe to those who choose to barely cover themselves at all. At the beach women are welcome to wear bikinis and men can don swimming shorts. Away from the beach it is more culturally acceptable for men to avoid wearing shorts or going shirtless and for women to avoid mini-skirts, midriff baring tops, and shorts. T-shirts or blouses and mid-length skirts or Capri pants for women are considered quite appropriate." (streetdirectory.com)
