Fully agree, wearing 1's all day is no fun at all, but if manpower is available, it's certainly handy to rotate the team so that at least one person is recognisable as a matelot at any given point.
One of the biggest bunch of cowboys with an identity crisis at PR events are Divers who wear a mix of desert camouflage, MTP, seamans jerseys, trackie tops, RayBans, chunky watches and nondescript woolly hats. I've even see some wearing WW2 navy-blue battle-dress tops, ffs. So much for a corporate image, then again resembling a bus driver doesn't do much for recruiting and "brand identity" either.
I'm surprised the RNRs 30 divers have managed to make such a negative impact on its 'corporate identity'. I think you also forgot to mention the tight branch branded rugby shorts.
