I've never worn race overalls but last time I donned a flying suit it took a few seconds to wriggle into over my normal clothes. So I agree with Small Rodent Driver - take your flying suit with you in the spammy and put it on before flying the proper aeroplane!
To wear it in the 182 would be, as I say, like wearing your race gear to the shops.
In saying this I am merely making an observation, not propounding some sort of religion. So it's not me who has the problem in making the observation (which is widely shared, BTW), it's the chap who feels the need to dress up as an airline captain to fly a 182 (excepting, as I say, those whose jobs mandate that). He's probably feeling the need to compensate for a lack somewhere.
