Except they don’t. Example, my fiancee is a fine dining chef, and as such has to keep her fingernails trimmed pretty short. If she decided to do the long nail thing, she’d be told to trim them. If you want to wear a party dress or beach attire to your office job, guess what, you can’t. If you wear metal jewelry and are an electrician, that stuff stays in your locker or home, same for food service.

Utility > vanity. If your aesthetic choices inhibit your ability to do your job, then you need to make different choices. This isn’t an accommodation for a disability or religious thing. If you want your appearance to get in the way of your work and it doesn’t impact your work, then you don’t need accommodation. If it’s uncomfortable then that’s your own damn fault.
