Madonna and Goldie have chosen rounder, larger lenses with a slight wrap around style. These larger frames are good if you have a rounder face or a more square jaw line. Get this look with the Sticky Fingers in Black Horn and the Siamese Dream in Black Horn.
Kate and Beyonce both have on slightly smaller frames. These frames are good if your face is smaller with a narrow chin. Get this look with the Heathrow in Polished Black or the 1984 in Black Horn.
