Honestly I care less about what uniform I have to wear and more about making sure DL pays for it.

I think RAH pilots have a very good uniform allowance policy, IIRC they get, each year, fully company paid
4x shirts
2x pants
1x hat
$150 for shoes

additionally they get a jacket and suitcase at regular intervals (I think 2 or 3 years) and ties and epaulettes as well.

if someone knows better than me please chime in.
