1958-59 - "Refrain" Yves Saint Laurent 4 Dior dress. "The full skirt and self bow marking the waist recall the designs of Dior from the early 1950s, however, the sacque-back treatment brings the dress more than up-to-the-moment. It heralds the A-line silhouette of the 1960s. Saint Laurent’s skill is evident in the way that the dress looks as if it is loose and free-flowing, belying the full rigid under structure that makes the design possible." MET Museum.
