Though, in the same line, decency rules aside, I'm always amazed how Supes can get with a destructo-wave that could level a mountain and his spandex only gets a couple tears in it.
Like ita said, in 1986 Byrne re-imagined Superman's invulnerability into an "electro-chemical aura" that radiated maybe a half inch out from his skin surface. So tight clothing and hair that lay close to his scalp were indestructible, while anything outside that could be burned or ripped as usual.
That actually made the magic weakness a lot more sensical. He's not actually made out of denser matter, it's just the bonds between his molecules are reinforced by an energy field—which magic doesn't seem to take note of.
Is the whole "vulnerable to magic" thing canon? Because it really bugs the heck out of me.
Yes, one of the two canonical weaknesses that go back decades.
In the original canon, Ma Kent took the blankets Kal was wrapped in from the rocket, unwove them down to threads, and made Clark's supersuit from that. The cloth was Kryptonian, thus invulnerable to rips, tears, punctures, and stains.
If it's invunerable, how could she tailor the material? Also, shouldn't the fact that they are Kryptonian have an effect like, well, Kryptonite?
Or am I being too logical?

I think only kryptonite acts like kryptonite -- other kryptonian artifacts (like the spaceship) have been shown to not interfere with his mojo.
The whole weaving story makes no sense. Sewing without cutting? Unlikely.
IIRC, the suit was knitted and Superboy did the cutting with his heat vision. And of course it doesn't make sense.

Okay, so imagining him in a chunky Arran sweater is really not helping.

Kryptonite is the result of the planet's explosion. Didn't exist before Krypton blew up, so anything that left Krypton before the explosion, i.e., the rocket, blankets, Kandor, etc., weren't converted.
She tailored the material by having young Clark break the threads with his heat vision.
eta: It wasn't so much knitted as woven, though.
Wasn't a lock of Superman's hair holding up weights in Superman IV?
