uniform re design

I am in need of a re-design of my workwear uniforms. Currently, I have traditional workwear uniforms, however I am interested in exploring different designs for this project. I am open to any suggestions about colors, patterns, materials, textures and so on, to create a modern and distinct look. The intended purpose for these uniforms will be workwear, so I would like the designs to be professional, timeless, and practical in order for my staff to be presentable and comfortable while they carry out their duties. I trust the expertise of the freelancer and am excited to see the end result.
