Another petticoat question!

[doxii.livejournal.com]

Hi everyone! I just got both this and this dress in my lucky pack and when I wear my petticoats that I usually wear with a-line dresses I look really deformed. Since the fabric is so light, all my petti-coats are free to be them selves and I look like a pumpkin. And I don't like it.
I'm planning on ordering from Taobao soon, anyone know if this or something like this would work with my dresses?

Bonus question!
I'm not sure how to even wear the Bianca jsk. Its really cute, but I can't find a away to make it look Lolita-ie. If anyone has coords wearing it, that would be a great help!

Thanks a bunch!
