And that's completely fine. However, my ooperator has multiple approved uniform vendors, and so the 'company look' already varies tremendously. Throw into that the fact that pretty much anything outside of "shirt, tie/crossover, pants, belt" is an ooptional uniform item, and we look like pirates anyway. So if we're going to choose our look, I'll look as professional as I can manage.
If you wore a bra, you'd probably appreciate some of the other deficiencies of the M&H shirts...
Believe me, if it were up to me, I'd prefer that the airline look was company-issued flight suits. I grew up wearing those*, and they're perfect for this 'pilot' job...
