Isla Size & Fit FAQs

Is Isla shallower than a deep square frame?

Its height reference is 40 mm. Compare that with a square pair you own to judge how much depth you prefer.

How wide is Isla across the whole front?

The overall width is marked 142 mm. Check it separately from the 52 mm single lens-width reference.

What should I compare around Isla’s 18 mm bridge?

Look at the curved centre opening beside your usual pair. The contour is useful alongside the spacing.

Will Isla’s side reach feel like a pair with longer arms?

The arms are marked 138 mm. Compare that length and tip bend with your current sunglasses before choosing.

Are Isla and Sienna the same stated size?

Their guides share 142 mm front, 52 mm lens width, 40 mm height reference, 18 mm bridge and 138 mm arms. The pictured finishes differ.

Measurements come from the supplied Isla size image. Compare them with a familiar pair; frame contours and personal preferences also influence fit.

 

Face Shapes and Sunglasses:
How to Find the Most Flattering Frames

Finding the right sunglasses starts with understanding your face shape. The best pair does more than protect your eyes — it balances your features, suits your personal style, and makes you feel instantly more confident.

There are no strict rules when it comes to style, but certain frame shapes naturally flatter different face shapes. Whether your look is bold, feminine, classic or trend-led, this guide will help you choose sunglasses that feel made for you.

Round Face Shape

A round face usually has soft curves, fuller cheeks, and a similar width and length. The goal is to add structure and create definition.

Best sunglasses for round faces:

• Square sunglasses
• Rectangular frames
• Flat-top sunglasses
• Cat-eye sunglasses
• Angular oversized styles

Square and rectangular frames help create contrast against softer features, while cat-eye sunglasses add a lifted, feminine shape. Flat-top frames are also a strong choice if you love a modern, fashion-forward look.

Style tip: Avoid very small round frames if you want more definition. Choose frames with sharper lines or a slightly oversized silhouette.

Oval Face Shape

An oval face is naturally balanced, with softly curved features and slightly wider cheekbones. This face shape is one of the most versatile and can wear most sunglasses styles beautifully.

Best sunglasses for oval faces:

• Oversized sunglasses
• Aviators
• Square frames
• Cat-eye sunglasses
• Round sunglasses
• Flat-top frames

Because oval faces suit many shapes, your choice can be guided more by your personal style. Oversized frames feel bold and polished, aviators feel relaxed, and cat-eye sunglasses add a feminine finish.

Style tip: Keep proportion in mind. Frames that are too wide or too tiny may interrupt the natural balance of your face.

Square Face Shape

A square face often has a strong jawline, broad forehead, and defined angles. The goal is to soften the face and create balance.

Best sunglasses for square faces:

• Round sunglasses
• Oval frames
• Aviators
• Soft cat-eye sunglasses
• Curved oversized frames

Round and oval sunglasses help soften sharper features, while aviators add a relaxed, timeless look. A softer cat-eye can also work beautifully because it adds lift without making the face appear too angular.

Style tip: Choose frames with curves or softer edges if you want a more balanced finish.

Heart-Shaped Face

A heart-shaped face usually has a wider forehead, high cheekbones, and a narrower chin. The goal is to balance the top of the face while enhancing the cheekbones.

Best sunglasses for heart-shaped faces:

• Cat-eye sunglasses
• Aviators
• Soft square frames
• Round sunglasses
• Lightweight oversized frames

Cat-eye sunglasses can look especially flattering because they follow the natural lift of the cheekbones. Aviators also work well because they help balance the forehead and chin.

Style tip: Avoid frames that feel too heavy across the top if you want a softer, more balanced look.

Long or Rectangular Face Shape

A long face shape has more length than width. The goal is to add width and create proportion.

Best sunglasses for long faces:

• Oversized sunglasses
• Wide square frames
• Statement sunglasses
• Large cat-eye frames
• Aviators

Oversized frames are especially flattering because they help break up the length of the face and create a more balanced shape. Wider frames can also make the face appear more proportioned.

Style tip: Avoid very narrow sunglasses if you want a fuller, more flattering look.

Diamond Face Shape

A diamond face shape usually has high cheekbones, a narrower forehead, and a narrower chin. The goal is to soften the cheekbones and add balance to the upper face.

Best sunglasses for diamond faces:

• Cat-eye sunglasses
• Oval frames
• Rimless or lighter frames
• Soft square sunglasses
• Round sunglasses

Cat-eye styles help lift the face, while oval and round frames soften angular cheekbones. Soft square frames can also work well when they are not too wide or heavy.

Style tip: Look for frames that highlight your cheekbones without overpowering your face.

Choosing Sunglasses That Suit Your Style

Face shape is a helpful guide, but your personal style matters just as much. The best sunglasses should suit your wardrobe, lifestyle, and the way you want to feel.

• Choose oversized sunglasses if you love a polished, confident look.
• Choose cat-eye sunglasses if you want something feminine, flattering, and stylish.
• Choose square sunglasses if you like modern, structured frames.
• Choose aviators if your style is relaxed, timeless, and effortless.
• Choose round sunglasses if you love a softer, retro-inspired look.
• Choose flat-top frames if you want something bold, modern, and fashion-forward.
