NEW YORK — Traces of Todd Oldham’s whimsy made an appearance at Escada’s fall-winter breakfast show last week, but there was appropriate restraint and an understanding of Escada’s customer in the collection. “The intent was never to create a revolution of design, but rather an evolution of design,” explains Ron Frasch, president and chief executive officer of Escada USA. “We’re moving along in a modern manner, opening the door for new customers, but we’re not after any extreme changes.” For instance, a mosaic of pearly white buttons livened up a three-piece suit, and animal prints and leather showed up on sophisticated fitted jackets and short skirts. There were also some great casual weekend looks: cozy oversized tunic sweaters, ribbed-knit leggings, shearling jackets and a quilted velvet animal print parka.
