I've been on the hunt for good organza petticoats so that I can avoid the problem of the all-too-soon deflation of tulle petticoats. I had bought a skirt from English Charm a few years ago which I still have and love, so I decided to try out their petticoats as well!
I purchased two petticoats in the cupcake shape, one in black and one in white. I'm very happy with what I received!http://www.englishcharm.com/catalog/foundations/cupcake/index.html
I placed my order on January 30th and got an email the next day acknowledging my order, saying that it would be approximately 2 weeks until the order was finished and shipped out. On February 10th, I was sent a partial refund as shipping ended up being cheaper than thought. The next day I got my tracking number, and it arrived at my house on the 14th.
Overall, everything is wonderful! The petticoats are extremely well made, the materials are soft and they fit great! The waist band is quite firm. Not tight to where it's painful or constricting, but it's definitely not going to be moving around! Which is great, because nobody likes a saggy petti. I personally like there to be more poof than less, so I will most likely wear both together or one with a smaller, 'dead' tulle petticoat. I hope that I won't have to replace them, unlike I do with my tulle ones. Or at least not for a while.
I hope this was helpful, and I highly recommend English Charm's petticoats!
