Some trends just won't quit — and there are a few that we're thrilled to see hangin' in there (as opposed to these). Exhibit A: the collar.The oft-dainty (but also quite edgy) accessory has become a permanent staple in our wardrobe, layered over simple sweaters, peeking beneath sleek blazers, and accenting our favorite dresses. And now, these fetching accessories have made their way into the limelight of Marni's winter collection. The eight pieces of black, white, and red neck candy are adorned by geometrical brooches, printed patterns, and bows — all creating a bold visual guaranteed to get plenty of people asking, "Where did you get that?" With the dreary and sludgy winter inevitably upon us, these playful pieces are certainly ideal for staying hot (under the collar) even when the temps start to drop. Shop them all at Marni boutiques and online, and jump ahead to preview all the whimsy styles that could even make Peter Pan jealous.
