Mayhaps a definition of "panache" is in order? I, as well as others, put forth their personal favorites, but panache may best be defined as "dash" or "verve". In that case I might add that defining the circumstances of use may well apply too. For example: In an alder-choked thicket in Alaskan bear country, panache may best be described as not a Colt Single Action .44 but rather a S&W M29 .44 with max velocity hard cast semi-wadcutters (or perhaps some of Mackay's .45 bear loads); or a pre-war Colt 6" Woodsman in upstate PA trout/deer woods in the off season vs. a Walther P-22; or a Colt 1911 .45 clutched in your hand versus a 9mm SIG stuffed in your pants on a Baltimore street at 1:00 AM on a Saturday night. Lookin' good doesn't count for much when practical considerations do, except when "stylin' " matters too.
