I discovered last night that Monster High girl tops fit my DZ Nono like a glove, so they should fit others of similar size like Pukipuki and maybe Obitsu. The plain dresses also fit nice but need hemmed a bit because of length.
Here's Amelia in a Draculara top:
I'll probably take the sleeves back a bit, but otherwise it is perfect.
Here she is in a Lagoona dress.
Too much length for standing, but it can be hemmed easily.
