Welcome to V.L.H
You buy one like everybody else
If you want something Xmas like, ask for the free shirt they give to temps. Otherwise you will have to buy a sweater like everyone else does, either from Tesco where you get a discount or some other shop of your choosing
Really???!!! i have no words
They do not have to be Tesco ones , any Christmas jumper is allowed .
Sounds like different stores have different rules. Unless it promotes another company, is rude or contains swearing, etc, we are allowed to wear anything Xmassy.
