Structurally Sound–Designer Italo Zucchelli delivers another technical lineup for Calvin Klein Collection’s fall/winter 2012 season. Combining elements of relaxed tailoring with a sporty attitude, long boxy silhouettes distinguish outerwear, cut from leather and nylon. Insulated for the cold, quilted jackets join a range of layered short-sleeved tops, paired with sweaters. Dressed with geometric graphics, the collection eventually makes a departure from the modern classics for an edgy touch of leather, adorning pants and blazer jackets for a strong finish.
