I really do think jeans and tees are best and simplest. At the Milan menswear spring / summer 2008 shows, for example,

there was the tragic (Klien)	… and the very tragic (Armani).
Some of the clothes were ridiculous (Biagiotti)	… or comical (Missoni).
There was the misbegotten (Gucci)	. . . and the merely colorful (McQueen).
Klien was hot, but sweaty	… and, thankfully, there was also the classic (Belstaff).
