Attire:  Shirt & shorts that are 'stretchy' (Ensure that attire is 'comfy' but not baggy – remember, you don’t want your shirt to go up over your head when you’re upside down!  Girls may also choose to wear a bodysuit).  Bare feet or gym slippers .  For safety reasons (everyone):  no jewelry (including exposed body piercings), no strings/hoods/belts, and HAIR that may obstruct vision when upside down must be tied back (please ask us for a hair elastic if you forget yours).
