I remember an old Superman comic. Trapped under a red sun, Supes is powerless, but his Kryptonian supersuit is still indestructible. Supes is bruised and battered but his clothes stay immaculate.
[iirc, the supersuit is made of Kryptonian tech and was originally blankets used to swaddle in infant Kal-El]
