almost bet, that this Buttercup's dress nobody remember.
Buttercup appears in this costume only for ca 1/2 minute to "plague"
prince Humperdinck with questions about Westley. A few images exists,
all of them show her only to her hips. But I like this dress...
Please, remember, this is a movie costume, not a period, and there I
did see princess seams - so I copied it.
