Eeaer smart cloth and shoes
It does not really matter, but be comfortable in what you wear, be clean and groomed, and casual.
I wore black jeans, smart shoes, a button up shirt under a jumper and I was fine.
Just dress smart but not too smart
Smart casual. Not too smart to look overdone, but not tracksuit attire. I wore checkered jeans and a nice top with some smart/ casual shoes (not trainers) and got the job. Dress appropriately to the role you’re applying for.
Smart trousers and shirt
Always dress smart. No trainers, jeans or t-shirts.
