Not sure which sunglasses suit you? Discover the best sunglasses styles for oval, square, heart-shaped and round faces, plus our top picks from Locello.

Buying sunglasses online can feel like a gamble. What looks flattering on a model in a photo doesn't always translate to your own face. The secret professional stylists use is simple: match your frame shape to your face shape. Get that right and any pair will look like it was made for you.

Below, we've broken down the four most common face shapes and the frame styles that flatter each one along with a few of our favourite Locello sunglasses to shop for every shape.

How Do I Know My Face Shape?

Look in the mirror and check where your face is widest and how sharp or soft your jawline is. Most faces fall into one of four categories: oval, square, heart-shaped, or round. Once you know yours, choosing flattering sunglasses gets a whole lot easier.

Best Sunglasses for an Oval Face

Lucky you. An oval face shape is naturally balanced, so almost every frame style works. This is the one face shape where you can afford to be a little daring: oversized frames, bold colours and statement shapes all look great without overwhelming your features.

Our picks:

• Serenity — a soft, rounded frame that plays up an oval face's natural symmetry
• Indy — a classic wayfarer-inspired shape for an easy, everyday look
  
  

Best Sunglasses for a Square Face

If your jawline is strong and your forehead and jaw are similar widths, you have a square face shape. The goal here is to soften those angles. Look for rounded or butterfly-shaped frames that bring curve and contrast to balance out sharper lines.

Our picks:

• Sabrina — a butterfly silhouette that softens strong angles beautifully
• Macey — oval lenses with just enough retro flair to offset a defined jaw
  
  

Best Sunglasses for a Heart-Shaped Face

A heart-shaped face is widest at the forehead and narrows to a delicate chin. To balance this out, look for frames with soft texture and a bit of extra width at the bottom — oversized styles tend to be especially flattering here, as they draw the eye evenly across the whole face.

Our picks:

• Kara — an oversized frame that beautifully balances a narrower chin
• Tessa — a soft cat-eye shape that complements the natural taper of a heart-shaped face
  
  
  

Best Sunglasses for a Round Face

Round faces have soft curves and similar width and length, with no strong angles. Rectangular or boxy frames add definition and structure, creating the appearance of more contour and length.

Our picks:

• Franca — a structured rectangular frame that adds definition
• Iris — an angular aviator-style shape that brings welcome contrast to soft curves
  
  
  

Final Tip: Trust the Try-On

Face-shape guidelines are a great starting point, but personal style always wins. If a pair makes you feel good, that's half the equation already sorted.
