For what it's worth,
My biggest objection to some things that get said here is the pressure it puts on the newly kilted to "wear this, but not that" or "look like me, but not like him". Ultimately, if you're wearing what YOU want to wear, and not what someone else has TOLD you to wear, then go for it. Yes, I like some clothing combinations better than others, but I don't get very worked up over what someone else chooses to wear.
About white hose: I have no experience with kilt rentals, so I don't see white hose as looking like they come from a rental shop. Others here who have the experience of renting a kilt do see them as "rental-looking".
Wear what you want.
