Do I need to buy my own bedding for Oxford University accommodation?

Hi, I'm aware this is probably a bit of a stupid question, but I recently attended one of the Oxford Uni offer holder days for St Anne's college and the way the Head of Accommodation was talking about cleaning / doing the laundry really made it sound like the college would be providing bed sheets / duvet covers for us. I am trying to get organised and as such am starting to buy things I will need at uni and I am wondering whether or not it is therefore necessary to buy bed linens. I will likely buy some anyways to be able to have a bit of control over my space and to add my own touch, but it's always good to know. Can anyone clarify? Thanks!

My college didn't provide bed sheets or duvet covers - I imagine this is probably also true of Anne's, but you can email them to confirm.
