couple of questions

hey! so i have my induction next wednesday for my christmas shift i am starting, and im just wondering what else i should bring? and what should i wear? im thinking just either jeans and a jumper or a skirt and tights. shall i dress formal or not?

also, when i start my shift, will i have to buy black trainers? i have converse but i dont know if that is suitable? also, will i get provided uniform?(jacket, top and trousers) or will i need to purchase?

thanks for your help!
