You are given a uniform, good luck trying to get spares if yours rip
Volunteers can wear pretty much anything but have to wear safety shoes in the warehouse.
Casual can wear what you want no uniform
You can wear your own clothes when working on the shop floor
black leggings /trousers
closed flat shoes
Casual, i was able to wear jeans and a smart top and be comfortable while presentable.
Casual dress code on the shop floor
Didn't really have a strict dress code but I was a volunteer so not sure if that makes a difference.
Safety boots and smart casual
Where what you want as long as its sensible for work in a retail environment i personally wear a T shirt and cargo pants and a comfortable pair of shoes
