@Lady
first of all i would be careful, wearing the belt for 10 days without having an emergency system (as seldom as you need it) is risky, also i don't know how you are going to do it with hygiene?
to your original question. i have sometimes worn a slip over the belt and sometimes not, depending on how cold it is outside and what i was wearing. leggings or tights are also good for hiding the belt.
