Colorful Frocks for Your Mom

The locale: a sleek rooftop soiree

The dress: jersey fabric gown with halter, sweetheart neckline and ruched bodice. Tadashi, $328,

Why it works: "This elegant column gown gives a sleek, elongated look to the body, making it a flattering option for a dressy, formal affair," says Joanne. "The wide halter-top and sweetheart neckline combined with the fitted bodice of the gown creates a slight hourglass shape with complementary curves. It’s ideal for moms who want to show off their shoulders."
