Romanticized robe

In the mid seventeeth century a new fashion arose to have a ladys portrait painted in a state of undress, wearing only a loosley fastened gown. The style is shown in many of the portraits by Peter Lely, as seen in his portrait of the mistress of Charles II, Nell Gwynn

Although this style does not directly represent true fashion of the time, looser gowns were beginning to be worn. I quite like the idea of Poppea being shown in a dress like this as it hints at her sexual relationships with men, both Ottone and Nero, and also suggests a looseness of character.

I also really like this image of Barbara Villiers, another of Charles II mistresses. i like the way that it is fastened up the front of the dress with buttons/clasps. Perhaps for Poppea i could use elements of both these dresses
