If you want something for class and are pretty sure you will continue dancing for a bit:

yoga pants or similar
crop top or fitted stretch top
several decent bras to wear beneath it
ballet slippers
warm coverup (like a hoodie or sweatshirt, for those cold studio days)
a simple hip scarf or belt of your choice, preferably not coined

and then:

veil (we start with inexpensive chiffon)
zills (not too big to start with)
a cane (if you know you will be doing some folk study)
