Okay, I'm going to premise this with the fact that I am a VERY NEW lolita. Not even a petticoat to my name. So I ordered one from a department store. It arrived today and brought along with it disappointment. I could barely get it on (although I'll blame that on the fact that it was a child's sized thing) and it was barely poufy.
So now my options are: A. Add a thing to the waistband as well as extra tule (which would also make me swap out the lace so it all matched) B. Return it and just make my own. C. Return it and buy a petticoat from Bodyline or F+F or My Lolita Dress .com. (Reviews would be helpful here).
