Kids may not know all the music from the 1950s, but this fall they will tune in to the clothes. The look is not far from the preppy styles that kids know well, but putting together the clothes the way they were worn in the 1950s makes them more fun, more grown-up, to wear.

Big letter sweaters, kilts, argyles, saddles shoes, loafers and theme sweaters all will go back to school in small and big sizes and in bright colors that were unheard of way back in the 1950s. And the '50s look is just as likely to show up in classroom in France or in Japan, where boys and girls turn out on Sunday afternoons to dance the Lindy in circle skirts or Elvis pompadours.
