Delicate rows of ruffles adorn the front of the sophisticated frock on the left by designer Robert Rodriguez, which retails for $320 at stores like Intermix and Neiman Marcus. If you like the concept but can't come up with the cash, then Forever 21 has you covered with their "Miriam" chiffon dress (right). It's got all the key features of the designer garment - delicious ruffles, sexy halter neckline, pleated skirt - and it comes in better colors: bright fuchsia or royal blue. Get one of each, we won't tell.
