Help!! Directions to Next on Oxford Street please!!?

I have a job interview at Next on Oxford Street tomorrow but don't know how to get there from the tube station and don't really want to waste time looking for it lol so i would really appreciate it if someone could give me some really simple straightforward directions to walk to the shop from oxford circus tube station, as stupid as that may sound. I've tried google maps n it gave me a route but i guess im just paranoid that iv done it wrong and will end up going to the wrong place lol. The shop's address is 201-203 oxfrd street. Thankk youuu!!!! =] x
