I actually have something similar to this dress that I found at the op shop. I have worn it out once and I did not feel comfortable wearing it because of bit's of flab and boob were overflowing but I am keeping the dress because 1. the sheer par of that dress is made out of silk. 2. It's really really pretty and 3. It was a steal for $10.
I will post a photo of it soon once I dusted my camera and if the sun comes out today.
