Nine West NW126S vs. NW634S: Metal Aviator or Plastic Square?
Both the NW126S and NW634S represent Nine West's commitment to accessible designer eyewear, but they serve different style preferences. The NW126S features a timeless metal pilot frame with stainless steel construction, while the NW634S offers a modern square plastic frame design.
The NW126S pilot shape is more universally flattering, particularly for square and oval face shapes, thanks to its rounded teardrop lenses that soften angular features. The lightweight stainless steel construction (58-14-135mm) makes these comfortable for all-day wear and resistant to corrosion. At $90.58-$101.54, they're also the more budget-friendly option.
The NW634S takes a bolder approach with full-rim plastic frames in a square lens shape. This contemporary style appeals to fashion-forward wearers looking for statement eyewear. However, plastic frames tend to be heavier than metal, and the square shape works best on round or oval faces rather than angular ones. The NW634S is priced slightly higher at $101.54-$128.70.
Choose the NW126S if: You want a classic, versatile style that works for multiple occasions, prefer lightweight metal frames, or have a square or heart-shaped face. The pilot shape is a timeless investment that never goes out of style.
Choose the NW634S if: You're drawn to contemporary square frames, want a bolder fashion statement, or have a round face that benefits from angular frame shapes. The plastic construction offers more color variety and a modern aesthetic.
