In the real world a pair of purple jeans would be obliterated instead of becoming purple cutoffs if the wearer gained 1500lbs of muscle mass while wearing them.In the real world, there are garments that make use of nude and clear plastic materials such that they stay on when they don't look like they should. Mind you, most of those aren't built to withstand the rigors of super-powered battle, so it becomes a questionable argument.
And energy blasts that cut through reinforced concrete should make short work of most spandex or cotton/poly blends.
