Growing into Giant

A man is getting ready for a concert when all of a sudden a strange wave comes over him.  out of nowhere, his body begins to grow at a rapid rate making his clothes tighter.  his socks could bear no more and shredded apart.  the button on his jeans then popped exposing his underwear.  his formerly loose shirt was too tight and began to rip apart as well, followed shortly by his jeans.  both his shirt and jeans fell to the floor leaving him in just his underwear, but they wouldn't last long.  his ass swallowed up his briefs making them look like a thong, before they started to rip too and fell off his body, leaving him totally naked.
