we do have one full day of training on grooming that focuses on image and uniform. It's pretty important to the airline. The red lipstick is pretty signature, in whichever shade suits your skin tone (it also must match the hat). They had a bunch of different Clarins shades for us to try on when we first got our uniforms.
While the airline industry has evolved past the harsh beauty standards once placed on female flight attendants, the profession still requires employees to dress the part. Though there is no doubt that aircraft safety is the primary (and extremely demanding) job responsibility of a flight attendant, there is also a deeply rooted, historical style element amongst cabin crews, especially when it comes to their uniforms.
