Into Polite Society? WIP

This was inspired by a conversation I had with a friend whose school is having a debutante ball for the Year 11s; we were talking about how an event where girls had to make their debut into polite society and wear five layers of puffy white taffeta could be made bearable for boys and tomboys. I came up with the idea of switching the traditional outfits- the guy would wear a white suit whit a white ruffled shirt and the girl would wear something like... well this. It's a tuxedo-dress! (Hmmm...drexedo? Tuxedress? )
It's a WIP b/c I haven't yet decided whether to add the guy and his costume, and I still have to finish the staircase.
Thankyou Jesse for the inspiration, and thankyou in advance to who shall be forced to make this dress for me !
