What are some good makeup/accessory ideas for the following costume? (please see details)

This is going to be my costume for Halloween: http://www.milanoo.com/Royal-Blue-And-Black-Bandage-Cotton-Classic-Lolita-Dress-p34156.html

The only thing is, my favorite part of Halloween is putting my artistic capabilities to good use with creative makeup, and I simply can’t think of a good idea for this costume. Does anyone have any ideas for makeup and/or hair? For the makeup, I’d prefer it to not be overkill, but not simple/basic either.
