What should I wear to tafe?

It’s summer where I live, so it’s quite warm and humid. I’m attending tafe and starting next week. They advised us to wear comfortable clothes. I’m wondering if I should wear a modest sundress or some yoga pants and a loose T shirt? These also look modest on me, as I have a big bum and big thighs, so I wear black pants and my T shirts cover the tops of my thighs.

I will be studying to be a special education teacher’s aide. My goal is to look decent enough, but also modest.
