Profile

Allen Small

Whether you're at your local park or the Riviera, Dion brings the Cannes supermodel energy. Oversized, sassy and ultimately classy. Crafted from quality acetate, this big feminine shape boasts a thick nose bridge, ensuring a sturdy, reliable feel.

If you thought Alfred was a charmer, just wait until you meet Alfred Large. Same handsome looks, this time on a super-size frame and suitable for wider faces.

If you’re looking for a bold, extra large frame with bucket-loads of character, then Hudson is your guy.

Hudson

Make way for Mac, the rugged rockstar that never ages. We updated a time-tested angular, square shape with a thicker frame and stronger inclination, so expect a little more impact. You can handle it.

A classic chunky square frame that adds a touch of class to any look, chart-topper Bobby Large is revamped and ready to roll.

Twiggy’s in the house so get ready to step into your 60s icon era. The frame that guarantees a touch of swinging attitude, with a softened square shape and exactly the right amount of look-at-me largeness.

It’s the 70’s in Los Angeles. You’re heading to a film screening. You’re wearing a funky suit. All that’s missing is a pair of groovy shades to go with it. That’s where Pablo comes in. These oversized sunglasses are the retro-chic staple to make your day feel like a movie. Limited prescription only.

Pablo

Teddy is a classic staple that doesn’t like to hide. These bold, thick frames have a sharp finish and a subtle diamond-shaped silhouette. Yes, that means they make you look good even under pressure. 

Teddy

A Strong and sturdy frame, Allen’s straight, strict shape exudes classic style.

Go big or go home. We decided with GANNI to make that Antonio's motto. This oversized, irregular frame is the stuff of retro dreams. Its large square lenses are slightly tilted for that extra bit of cool. Emphasis on "extra."

Antonio x GANNI

Oh, Sofia. This wild thing will get you singing in the rain and making your own kombucha.

Sofia

If you’re into that low-key 90s vibe, then allow us to introduce Curtis. We scaled down and slightly rounded a square shape for a decidedly fresh feel. Cut from sleek stainless steel, he’s light and durable too.

Curtis

Although supremely supersized, we balanced Nicole’s exaggerated proportions to feel more heavenly than heavy. Full discloser: these shades are basically a right of passage to show up fashionably late. 

Nicole

Young Bobby is somewhat of a legend on the playground. The classic square frame gives off stylish confidence, made more fun with whimsical colours. This young one comes with flex hinges, making it almost unbreakable while showing off on the monkey bars.

Young Bobby

Meet GANNI's fresh take on Twiggy. This staple has a softened square shape with just the right amount of look-at-me largeness. For this exclusive collab.
This colourway is Acetate Renew Bio, made from cellulose and certified recycled contents (instead of fossil fuels), and bio-based plasticizers.

Twiggy x GANNI

Best believe Lil Allen is down with the kids. The fun-sized edition of our sturdy Allen frame offers the same oversized rockstar attitude but somehow looks even cooler when worn by little legends. The sunglasses come in deliciously bright hues and flex hinges to survive serious tumbles and falls.
