Hi,I finally decided on my dress today

yay!!!!!!!!!! It was one I have wanted but wrote a post awhile back that I wasn't sure about the material being silk. Anyway, I went to look at it again today with my mom and aunt and it looked a whole lot better. ( I think it was a new one) Its like a cinderella dress, so once I put on a big petty coat ( the one with the big wires in it, looks like a hola hoop, not sure what they are called) it was perfect. So my question is, which someone asked me is " can I sit with this on? I am guessing I can but it did make me think! I know its a silly question, but I have been thinking about it. Any help?
