Ah, wow, I had no idea of the significance of the dress. That IS pretty cool, in addition to everything awesome about it.
Other nice thing about the SAS appearance is that rhian is wearing a traditinal filipino dress that symbolizes modesty and submissiveness and invented under the patriarchal rule of the spanish. The fact that they let two women holding hands walk out like that on the show and basically letting them end that whole segment is strangely subversive to the whole notion of patriarchy.
