BABY, THE STARS SHINE BRIGHT's Sugar Rose Cake JSK in black. I bought this secondhand and just tried it on - but it just isn't flattering on me!
No flaws that I could see. Has a really cute cake print with little heart buttons attaching the waist ties! Also has shirring and corset lacing in the back, and a detachable bow with a pin.

Measurements from Lolibrary:
Bust: 33.85-36.61inch (86-93cm) (I have a 36 inch bust and this dress was hard to zip up and somewhat tight, so I would probably recommend it for no bigger than 35 inches)
Waist: 27.95-33.85inch (71-86cm)
Length: 35inch (89cm)
