How short should men's shorts be?

I've been seeing a lot of guys wearing fanny packs recently because their shorts are too short to carry phones/wallets/etc. Never thought I'd be in support of the fanny pack making a comeback but...here we are.
Many years ago, I had a teacher of Italian descent, who liked explaining her native culture to class. I remember her explaining that the reason some stylish Italian men carried purses is that their pants were so well tailored to their bodies, that it was impossible to put anything of substance in the pockets.
 
The USA reruns channel Heroes and Icons is showing the TV show VEGA$ (1978-81), there are quite a few scenes of guys in Speedos and Short Shorts :)
