Clothing: Please bring something you feel comfortable standing and moving in that also allows access to the tissues we’re working with.
The less clothing that’s covering your skin, generally speaking, the better, of course within your comfort range.
For most people, a normal underwear/bra setup serves this purpose. A swimsuit can also work well.
I’ll have a blanket for your warmth and comfort while you’re on the table, which will be most, but not all, of the session.
What else: a water bottle can be nice to hydrate before and after, though I’ll have water available, too. Other than that, just bring you!
