I get the impression from customers that they do appreciate an image from the pilots. However, it is not the one that VX is modeling. They appreciate a polite, trim, and neat professional. They like somebody who appears to be confident but does not display vanity.
Pilot appearance should convey something about a safe efficient flying experience. Customers want a smooth, uneventful ride. Faux hawks, club attire, and lack of neckwear don't convey this sentiment.
While I am sure that VX is crowded with seasoned professionals up front, the future uniform does not inspire that sentiment. Subtlety sells too.
