Morocco- what to pack for 3 week trip
 

We are traveling to Morocco in mid September, 3 weeks around the country. Was wondering what to pack? What would dress be while traveling during the day and at night for dinner at nice restaurants out and while eating in at the Riads. We are staying at 4-5 star hotels and nice Riads. Also first time in the country, any advice, we have private drivers and guides lined up. TIA!

Temps should be fairly mild, even hot, although perhaps cooler at night if in the mountains. From my own experience, dress style is casual. A lightweight pair of black pants and a nice top would be the extent of my dressing up.
