I don't believe you have never tried one for size.
At the risk of taking that remark seriously...
I have handled one a couple of times, but in most cases it's someone's personal attire so I wouldn't want to try it on.
There's also the matter of it being official regalia, and earning the right to wear it, so for the likes of me to plonk one on, even outside court, wouldn't go down well.
Controversially, the CPS prosecutors were given the right to wear a wig in Crown Court, even though they hadn't earned it, which didn't go down well with the crusty old members of the Bar.
The wigs are about £300, and the CPS prosecutors in Durham weren't inclined to buy their own, so CPS Durham bought a 'pool wig' for them to share.
