Also, T'Lar in The Search for Spock
wore quite a lot of makeup and a very elaborate headdress and robe. Some of that might have been worn solely because of the importance of the fal-tor-pan
ceremony held on Mount Seleya, but a lot of Vulcan women throughout the history of the franchise have had rather exotic and made-up appearances. They seem just as vain as Earth women even if their logical training and upbringing prevent them from expressing it.
Human instinct is pretty strong. You can't expect us to change overnight.
