The Sultan of Johar and his wife, Raja Zarith Sofiah.
The woman in pink is the Sultan's daughter-in-law, Che Puan Khaleeda Binti Bustamam. I'd love to get a better look at her jewellery.
I believe that these are other Malaysian royals. The woman in yellow, second from the left is Sultanah Kalsom of Pahang.
The woman in yellow, fourth from the right is Sultanah Nur Zahirah of Terengganu and the woman in pink, second from the left is Queen Saleha of Brunei.
