As a start, I'm a middle aged guy who has some thoughts... and I think my thoughts are that I shouldn't really have an opinion beyond a desire to know who works for the company, and hopefully an idea what their role is in that company, based on their clothing. I want the employees to feel good about the clothes that they wear and that they are appropriately professional, whatever that means. Beyond that, I don't really feel it's my business to have an opinion about how they look, what material something is, or even how it fits. That's between Delta's employees and Delta management.
