I have one similar to this and they fit beautifully and have plenty of room for various body shapes/sizes without losing their shape. The material feel very sensual on and it is oh so flattering too.
If you want to try it then why not? Peoples opinions are irrelevant, if you like the idea then go for it! I Think it is open crotch (mine is) so like a previous poster suggested a nice mini would look gorgeous with it 
Hope you do decide to buy it and enjoy wearing it!!! xx
