Bartolomeo Veneto painted a famous controversial portrait of Lucrezia wearing white with one breast bared. Perhaps this was the inspiration for the white wedding gown. I would not be surprised. The portrait is "More Sinned Against than Sinning." The rest of the costuming is pretty much impeccable. Just look at art to verify it. Derek Jacobi stars in it, always a guarantee for a quality production. NB: some should study history before judging erroneously what they don't know.
