In a world where people are forced to wear hi-vis and safety goggles, I don't think people on a shop floor are going to particularly care about looking good if it makes their job easier.
Don't forget those formal white (OK, heavy canvas or leather) gloves to complete your outfit, nor the essential steel-toe boots! They're at the peak of high-fashion footwear. You can look even better if you're only on the shop floor part-time and get to don colorful Oshatoes over your dress shoes: https://www.oshatoes.com/collections/toe-protection/products...
