Wearing full uniform and a set of stripes is usually the way to impress
Long sleeve pilot shirt with epaulettes (the straps upon which the bars are mounted), slacks (black or blue whatever suits the particular shirt), black dress shoes
I hope you were taking the piss!!!
'Cause I most certainly was.
Quickest way to get your resume in the bin is to appear in uniform with a set of Raybans strapped to your head. Smart casual is the preferred option, so a nice shirt and pants with polished shoes.
Have fun!
