Saint Laurent SL890 BETTY Sunglasses
Narrow Rectangular Sunglasses with Sharp Saint Laurent Proportions
The Saint Laurent SL 890 Betty combines elongated rectangular lines, a close-fitting silhouette, and polished acetate construction in a frame that feels sharp, sleek, and distinctly fashion-driven.
Designed with narrow proportions that sit close to the face, the silhouette creates a stronger and more directional look than a classic rectangular frame. The elongated shape sharpens the expression naturally, while the slim profile keeps the overall appearance controlled and refined rather than oversized.
Crafted in Italy from premium acetate, the SL 890 Betty features a hand-polished lacquered finish that enhances the depth and richness of the frame. Slim temples and subtle Saint Laurent detailing preserve the minimal structure and keep the focus on silhouette and proportion.
The dark tinted lenses provide full UVA and UVB protection while reinforcing the monochromatic character of the design. Combined with the streamlined shape, they give the frame a colder, more composed visual identity associated with Saint Laurent’s signature aesthetic.
What distinguishes the SL 890 Betty is its restraint. The silhouette creates impact through narrow proportions, clean geometry, and close-to-the-face structure rather than exaggerated volume or decorative elements.
The frame feels sleek, controlled, and intentionally sharp — a stronger interpretation of minimalist luxury eyewear.
SAINT LAURENT — sharp minimalism through narrow proportion and controlled structure.

Size and Fit
I understand the importance of a proper fitting frame. Not every frame fits every face, which is why we have a wide selection of frame sizes to choose from.
There are no rules – just guidelines we suggest to help you find frames that not only look great but fit perfectly.
HOW WE SEE YOU
Size definitely matters. We determine size by the width of your face. We offer multiple sizes so that you can find the right frame for your face.
If you already wear glasses, we recommend looking at your current pair as a size reference. If you still have doubt we are here to help you with professional advice.
BRIDGE – INTERNATIONAL OR ALTERNATIVE/ASIAN FITTING
Acetate nose pads: Made from Italian or Japanese acetate. Comfortable, classic fit. Recommended for those who prefer the look of acetate.
Metal nose pads: Made from silicone or ceramic. Soft, flexible, anti-allergic. Recommended for those needing additional support for less prominent nose bridges or more prominent cheekbones.
FIND YOUR FACE SHAPE
Oval
Balanced and slightly narrow, the oval face is a canvas for experimentation. Almost any silhouette will look good on you. Luxury lies in the choice.
Heart
Wide forehead, high cheekbones and a narrow jawline. This shape is expressive and romantic. Choose a sharp-edged or gently curved cat-eye shape or a balanced aviator shape that softens the contrast and emphasizes the proportions.
Square
A strong jawline, higher forehead, and symmetrical brow line characterize this sculptural face. Choose rounded or elliptical frames to soften the angularity and enhance natural strength with graceful restraint.
Rectangle
Long and slender, with delicate lines. Here, it is worth choosing frames that give width and dimension to create harmony. Oversized or deep-set profiles bring visual balance to the more elongated shape.
Triangle
Defined by a more pronounced jawline, a finer forehead, and an elegant contrast between cheekbones. Choose round or square frames with sharp lines that harmoniously balance the proportions.
Round
A full face and delicate contours radiate warmth and symmetry. In contrast, square frames elongate and define the face.
There are no rules – just guidelines. Explore, get inspired and choose frames that make you feel confident, happy and most importantly, yourself.
