13/04/2026The Rose Gold frame with Green lenses is everything! Such a unique color combination that gets compliments every time I wear them. The metal frame has this delicate shine that catches the light beautifully. As someone who identifies as female, I love how these sunglasses add a touch of elegance to any outfit. The materials feel high-quality and durable.

10/04/2026Opted for the Silver frame with Blue lenses - modern and sleek! The metal construction feels solid yet comfortable. What I appreciate most is the gender-neutral design; it doesn't lean too far in any direction. The color combination is perfect for summer beach days and city walks alike. Definitely my new go-to sunglasses for daily use.

07/04/2026Went with the Black frame and Grey lenses - clean, professional, and versatile. The acetate material has a nice weight to it, not too light but comfortable for all-day wear. The unisex design works perfectly for me as a man; it's not overly masculine or feminine. Great for driving and outdoor activities with excellent UV protection.

07/04/2026Brown frame with Brown lenses create such a warm, harmonious look! The acetate material gives them a classic feel that never goes out of style. As a woman, I find the shape particularly flattering - it balances my face nicely. The colors work well with my skin tone and most of my wardrobe. Comfortable enough to wear for hours without any pressure points.

04/04/2026Got the Gunmetal frame with Grey lenses - understated and cool. The metal frame has a matte finish that looks premium without being flashy. The unisex design is perfect as I prefer accessories that don't conform to traditional gender norms. Excellent build quality and the materials feel like they'll last for seasons to come. Great for both men and women who appreciate minimalist style.

27/03/2026I chose the Gold frame with Brown lenses and I'm absolutely in love! The combination gives such a vintage yet sophisticated look. The metal material feels premium and sturdy on my face. As a woman, I appreciate how these sunglasses complement my facial features without being too bulky. Perfect for both casual outings and dressier occasions!
