Design for a t-shirt and hoodie

We are a primary teachers work-life balance coaching company. Clients have requested our coaching slogans on clothing. I'd like to start with 'slow down to speed up' Simple design with maybe a 60's type swirl design and links to primary school teachers. Though I don't have a set idea I'm looking for something calm and clean but colorful. Balance for teachers is a movement so that type of energy in the design and to include #balanceforteachers

Colours: Purple #8809F6, White, Green #77F609

To be used on a t-shirt and hoodie. Hoodies will be black or grey and t-shirt most likely black or grey too

Slogan - slow down to speed up
#balanceforteachers

Would like some ideas sent first of what you would envisage as a design.
