The fabulous courtesan, Madame de Pompadour, modeling the iconic look of a Rococo gown in her day.
Although I think most lolita dresses only really possess a small facet of a typical Rococo gown or even none at all. So when brands really does do a truly Rococo inspired dress, I immediately stand up and take notice.
The latest being Innocent World's Victorica Dress
It's called Victorica, alluding to Victorian?, but one can see its heavy Rococo influences. The characteristic half-sleeves, ribboned bodice and what I term as the 'curtained' skirt, all screams Rococo to me.
At one time or another, brands would come up with their versions of a Rococo lolita dress. My opinion is Juliette et Justine does it the most often and accompanied by very exotic sounding French terms.
Juliette et Justine's crème sucrée et fleur set.
