Being comfortable is a priority here so bearing in mind you will be lying on the floor for part of the day, so in addition to the list below, bring whatever will make you most comfortable By all means call me if you are not sure (contact details below).
Again it is about being comfortable as well as being able to move easily, so loose comfortable clothing is ideal. You may also want to bring layers for when you cool down and I always like to have a pair of warm fluffy socks on standby.
