Hi Mariem,Please tell us a little more about the family. Do they belong to the middle class or a lower class?
I used to visit a wonderful family in a quite poor Cairo area. I used to come with some typical food items from my country, you can find them in Egypt but it was unaffordable for them. The women of the family also really enjoyed any beauty stuff like toners, creams, lipsticks and so on, which are also expensive in Egypt. Funny shower gels for the kids, with nice colors and smells.
Everyone was so happy with these gifts! Anyway, Egyptians are so warm and kind people, they will love everything you brought them!
Lingerie isn't something I would think about. First of all you don't know their size, and you can't ask your male friend to tell you...
Good luck Mariem!
