Sonia Rykiel may be the grande dame of Paris ready-to-wear, but she ain't no prude. Her summer collection, true to her '70s roots, was full of little sexpot knits—not to mention a few unscheduled poppings-out of bosoms.

Rykiel proved here that there's nowhere knitwear can't follow when a trend is in the offing. She did slouchy overalls on elongated straps, which were sometimes worn in an offhand way, with the bib trailing down. Lurex stripes, floppy black knit hats (worn by every girl in the show) and her signature sweaters with glittery cartoons on the front looked as neatly current as they did 30 years ago. The runway problem came, though, when the more well-endowed models bounced along in the designer's ultra-skimpy knitted bra tops. Often the tiny triangles proved not quite up to their task of containment.
