When I think of Walmart I automatically think of the iconic blue vest, but those vests are going away! Walmart announced they are changing to a more modern and relaxed grey vest with neon trim. The trim will help customers spot employees quicker. The new vests will be made from recycled bottles and have bigger pockets than previous vests. Workers can now wear any solid-colored shirt. Walmart added blue to the mix of approved pants colors, making blue jeans work-appropriate attire.
