There's no mistaking Chanel's CC signature on Ashlee's arm, because it's spelled out boldly in pearls on her wide black Lucite cuff. When you have to wear the real thing, Bag Borrow or Steal rents the cuff bracelet by the week or month.
If the rental's out of your budget, search for Lucite bangles and cuffs on Etsy. You might be surprised how many are available -- not by Chanel, but maybe you'll be one of the first to discover an up and coming 21st Century jewelry designer.
