When I first thought what should Maura wear for the ball and what came to mind was a suit! :D
I got that idea from PGR Maid Cosplay by Toyotami kun

She looks cool in a suit plus she's stubborn about wearing dresses. She never felt comfortable in them but I drew her with dresses and I couldn't think of what kind of dress that suited her.

The dresses didn't look right. Not formal more like going out to town on a date or to church XD

So I'm thinking of deciding on the suit. What do you think?
