After seasons of 70s Bohemians, fashion skips back a decade with 60s Mod mania, complete with structured shapes, happy colors and plenty of minis. Maria Grazia Chiuri at Dior believes the look encapsulates what young customers are looking for right now: “Something graphic and clean, minimal and positive. Because I think we have to give an optimistic outlook to the future.”  The look evolves for next spring with nearly neon hues, eye-catching placed motifs and graphic cutouts, whether a squared-off neckline or triangular openings at midriff or sides. Items include sleeveless or halter-neck shifts and bright A-line miniskirts. Get ready for a new “youthquake”.
