This Buffy – Im Bann der Dämonen foto contains
brautjungfer and trauzeugin.
There might also be
abendkleid, abendessen kleid, formal, abendessen-kleid, and formale.
Really, really funny Buffy bloopers including a lot of language on SMG and James M.'s part and a little of Spuffy...um, "bumping uglies"...if Du catch my drift :D
