I feel sorry for people who work in supermarkets, the uniforms are not the best, i think they are designed with older people in mind. The Tesco one always looks ok though!! Better than the bright green asda one.
People who work in poundland though I presume they have a horrible uniform, and my friend used to work at the Co-op and always complained about navy blue trousers.
I used to work at a nursery and had to wear a bright green T-shirt, but I always managed to get away with wearing a black or white top, as I only worked part time (after school) and was well liked by the owner as well as the parents so I got away with it.
At the moment though I am enjoying that I will never have to wear a uniform again! At Topshop we just get to wear the latest fashions which I love, and we get uniform allowence every three months were we get 75% off a certain amount of items! DEFINETLY the best uniform!
