If you have a spare $10 or $12 lying around, here are a few flattering bargains at JC Penney. Peplum is big, and these are on sale.
The purple Bisou Bisou Keyhole-Back Peplum Top is $10 on clearance, and it comes in a variety of colors:
The black-and-white Worthington Button-Front Peplum Shirt is on clearance for $12 also at JC Penney.
Fresh and flattering — I need some retail therapy and these two just might do it for me. Of course, at these prices, sizes are limited.
