Buy a djellaba, a traditional, hooded robe. My husband bought a black one, charmed into believing he looked, “Like a typical Arab,” in it. It’s been a wonderful dressing gown for the last 12 years. The hood keeps out drafts and means it makes an ideal monk or Darth Vader costume for scaring children at Halloween.
In the souk in Marrakech, and most other North African souks.
