You wouldn't need any equipment of your own in your first class unless they have stated you need to bring any. Wear what you would wear if you were doing other exercise such as running etc but keep in mind you will need mobility in your shoulders and arms so don't wear anything to tight over the shoulders. Other than that turn up to the class and introduce yourself to the instructor and enjoy.

Assuming you won't be sparring soon, if at all, just standard workout clothes will do, tank top and running shorts or legging things. Handwraps would be good as well but they probably sell them there. And I doubt they would require you to bring your own gloves.

head protector and gloves

not much booty shorts and a vest will do ....
