God forbid you actually act like a professional and abide by your company policies. 1. If it's part of your company uniform, go for it. If not, don't. Your FOM is an FAA signed document. I'm pretty sure SWA has made it an optional item with epilates.
2. Wearing a uniform does have a safety aspect. During an evacuation pax and emergency personnel will go to you for guidance. A captain who once had to perform an evacuation commented on this to me. Most pax naturally congregated around him as soon as he got off the airplane and emergency personnel immediately came up to him and asked him for pax count. They knew who the captain was by his uniform.
3. The airline uniform has been standard long before I was born, which is probably before you were born. Some have changed recently due to mergers, but I guarantee your airline had a uniform policy when you were hired and I can also guarantee you didn't raise any objections to it. If someone is paying your check and wants you to wear a uniform, wear the uniform.

Being a professional is trying to do the right thing all the time, not just when it suits you. Doing even the little things right, not deciding for yourself which policies you will follow and which ones you won't.
