The dress: One shouldered silk barathea with fluted skirt and hand-dyed ruffled sweep. Waterlily, $42,90, Junko Yoshioka 212-206-9302
Why it fits: The aisle may be the bride's runway, but your avant-garde mom can make it memorable too. Though this dress is dramatic, its delicate shade, billowing skirt, and feminine shape will highlight your mom's form as well as style.
