Djellabas are fairly standard fare come Resort time, but not in the crisp, preppy plaid they showed theirs in, and not with shirt cuffs, either. It's elements of surprise and attentive little details like those that have captured fashion's attention, although it probably hasn't hurt that they're the daughters of C.

Let's call it a beginner's mistake. But if that was a slight miscalculation, there were plenty of other winning pieces. A denim barn jacket with a red shearling collar will be a popular item in store, as will the knits. Sweaters continue to be a highlight for Trademark; this season it was the trompe l'oeil twinset in royal blue and red that really stood out. Another clever idea: a silk evening pajama set in navy and off-white for the girl who wants to look pulled together without pulling on a dress—offbeat, in the best way.
