Choosing the right sunglasses is about more than style. The best pair should fit your face shape, match your personal style, and meet your everyday needs—while protecting your eyes from UV rays. If you’ve ever asked yourself “what sunglasses fit me?”, this guide breaks the process down into simple, practical steps. You’ll learn how to identify your face shape, choose flattering frame styles, pick the right colors, and decide which lenses work best for your lifestyle. By the end, you’ll know exactly what to look for when shopping for sunglasses you’ll feel confident wearing year-round.

Choosing the right frame shape is the foundation of finding sunglasses that truly suit you. While there are dozens of frame styles available, the most flattering options usually balance and contrast your natural facial features

Most people fall into one of five main face shapes:

• Square

• Heart

• Oval

• Round

• Diamond

If you’re unsure of your face shape, look straight into a mirror and trace the outline of your face with a washable marker or soap. The shape it most closely resembles is your face shape.

Remember: face shape guidelines are helpful, but personal comfort and confidence always come first.

If you have a square face, your features are defined by a strong jawline and a broad forehead. The goal is to soften angles with curved or fluid shapes.

Best frame styles:

• Oval frames

• Round frames

• Aviator sunglasses

• Cat-eye frames

Avoid: square or rectangular frames, which can exaggerate sharp angles.

Heart-shaped faces are wider at the forehead and narrower at the chin. Frames that add balance to the lower half of the face work best.

Best frame styles:

• Cat-eye sunglasses

• Rectangular frames

• Square frames

These styles visually balance the forehead while complementing softer facial features.

Oval faces are naturally balanced, with softly rounded features and slightly longer proportions. This face shape can wear almost any frame style.

Best frame styles:

• Square frames

• Oversized frames

• Aviator sunglasses

• Rectangular frames

Wider or structured frames add contrast and definition.

Round faces feature soft curves and equal width and length. Angular frames help add structure and definition.

Best frame styles:

• Rectangular frames

• Square frames

• Club-style frames

These shapes create contrast and visually lengthen the face.

Diamond faces are narrow at the forehead and chin, with wider cheekbones. The goal is to soften angles and highlight symmetry.

Best frame styles:

• Browline frames

• Round frames

• Oval frames

These styles balance cheekbones and create a harmonious look.

Frame color plays a major role in how sunglasses complement your skin tone and wardrobe.

• Cool undertones: veins appear blue or purple; silver jewelry is more flattering

• Warm undertones: veins appear green; gold jewelry is more flattering

• Neutral undertones: a mix of both

• Cool undertones: black, blue, silver, purple, emerald

• Warm undertones: tortoise, brown, gold, olive, amber

• Neutral undertones: most colors work well

If you prefer versatility, neutral frames like black, tortoise, or clear pair easily with most outfits.

The best sunglasses aren’t just flattering—they fit your daily needs.

Lightweight frames and neutral colors work well for daily wear.

If you need help seeing up close outdoors, reading sunglasses offer UV protection with magnification. Options include:

A great pair of sunglasses should:

• Sit comfortably on the nose

• Stay secure without pinching

• Align properly with your eyes

• Feel balanced and lightweight

Fit, function, and comfort are just as important as style.

The perfect sunglasses combine flattering shape, complementary color, functional lenses, and a comfortable fit. By understanding your face shape, skin tone, and lifestyle needs, you can confidently choose sunglasses that look great and perform well year-round.

After you pick what frame shape you want, it’s time to pick your frame color! Here are a few of our favorite tips for picking what color sunglasses to wear all year long:

• First, find your skin’s undertones. These are the colors underneath your skin color that determine if you have cool or warm undertones.
  
  
• If you have cool undertones, you will likely be able to see your veins pop out in vivid blues or greens. If you have warm undertones, your veins may be harder to find and more neutral. Cool undertones also look best with silver jewelry, while warm undertones look best with gold.
  
  
• Once you determine your skin’s undertones, you can find the colors that go best with your skin! If you have cool undertones, wear blues, purples, silver, or emerald greens. If your undertones are warmer, you’ll probably look best in earthy tones like tortoise, brown, blue and light green.
  
  
• If you aren’t sure what your undertones are or just prefer to, you can wear more neutral color glasses.
  
  
• Pick colors that go with your wardrobe! You want your sunglasses to match what you’ll be wearing. If your closet is mostly full of floral sundresses and bright bikinis, find sunglasses to match! If it’s full of earth-toned classic pieces or neutral colors, find frames to complement your style.

Reading sunglasses are a great way to protect your eyes from the sun while still providing the help you need to read up close. You can choose between reader segment style SunReaders® or a fully magnified SunReaders® to keep your vision clear while outdoors.

The perfect pair of sunglasses is more than just a stylish frame. Knowing what frame complements your face shape the best, knowing what colors go with your skin tones and your wardrobe, and knowing what type of sunglasses to invest in are key to picking out the perfect pair.
