After a successful months-long run in resisting buying duplicates, I recently fell back into old habits. First, I tracked down the Theory Annea Caledon Sleeveless Jacket in both black and white (still available at Theory outlets) and then bought the Rebecca Taylor tweed with leather dress and top.

Unnecessary? absolutely. But I regret nothing.

What clothing items do you have multiples of? Or do you have an unconditional ban on duplicates?
