Max9 nothing to do with being skinny, everything to do with the curves!
I have lots of corsets, they're actually fantastic for making a chastity belt more comfortable around the hips. It helps to spread the load evenly. If I wore my belt in winter I would wear a simple body shaper / singlet just for the extra comfort.
I have other ones too, but they are ummm... not exactly suitable for everyday wear. π
