We we first meet other Vulcan they wore this
Men wearing what I want to call tunic over black shirts and leggings. T'Pring in a silver minidress and T'Pau in slacks and a gauzy flowing covering Vulcan formal wear? (It is a wedding) I think they might been going for a Asian flare.
When Sarak and Amanda show up, Sarek is in a Vulcan "business suit" and Amanda wears colorful full length dresses. Though her last outfit seems to be slacks. Being human, she might chose colorful outfits to "rebel" a little
Our last TOS Vulcan is Surak. He sporting a tunic. Perhaps to give a "Ancient times" feeling.
