Just put the bloody thing on for the 5 minutes you spend on an apron. It isn't an inconvenience at all, and if it does annoy you, then you're easily annoyed and in need of some acupuncture!
I don't see why people make such a fuss about high-vis jackets. What is wrong with putting it on for 5 minutes, so you can do your walk around on the apron? Where is the problem in that? Do you think it "cramps" your style? You are paid to fly and do so safely. If 'looking good' is your priority then god help us.
