Qatarias wear black shaylas (head covering with no pin or clip just different ways of wrapping it). Often we wear our long hair up so the shayla can be wrapped more easily) and black abayas which skiff the floor and cover our shoes. The abayas are supposed to be long and flowing, hence the feeling of elgance if worn with high(ish) heels.

Hijab is the universal term for covering your hair.
