Flexing is what this style does best, with a sleek geometric frame that looks great from every angle. A modern interpretation of the classic butterfly shape, the ultra-fresh RB3731 Anh features a straight browline and comes with a variety of pastel-colored lenses for a bold, standout look that wont fail- to get you noticed. Recalling the trends of the early 2000s, the style is available in classic metal finishes with bio-nylon lenses, in a range of four colors from the classic black to the fresh lilac, green apple or cherry tones.
