Fit & sizing tips (petite to roomy)
If lens width numbers look cryptic, start with what feels natural: many Cosette frames fall around 53–55 mm lens width, 15–17 mm bridge, and 135–145 mm temples, giving a relaxed, stay-put fit for most faces. Petite faces may prefer 53 mm with slimmer bridges; broader faces often like 55 mm or a slightly wider bridge for balance.
Lens note: Eyeglasses arrive with demo lenses (non-prescription); your optician can fit your Rx easily.
Materials & care for daily wear
Most styles use lightweight plastics and smooth acetate fronts that resist everyday scuffs. Select frames add spring hinges for extra give when you slip them on and off. To keep that showroom sheen, rinse with lukewarm water, dab a drop of mild soap, then dry with a microfiber cloth—no hot water, no harsh chemicals.
Face-shape pointers for quick picks
Rectangular fronts sharpen soft, round features; oval and gentle geometric shapes soften strong jawlines. If you love patterns, tortoise warms up complexions; blush crystal reads airy and modern. Want a deeper dive? See our face-shape tips for fast, visual shortcuts.

FAQ
Do Cosette frames work for petite faces?
Yes. Look for lens widths near 53 mm and narrower bridges (around 15-16 mm) to prevent sliding. Slimmer temples also help balance small features. If you are between sizes, compare your current frame measurements printed inside the temple to find the closest match without guesswork.
What sizes do most styles use?
Many pieces cluster around 53-55 mm lens width, 15-17 mm bridge, and 135-145 mm temple length. These measurements fit a wide range of medium faces. Use our product pages for exact numbers and favor frames with spring hinges if you want a little extra flex at the temples.
Do the glasses include a case?
Original designer cases are not included, but orders ship with a protective generic hard case or pouch so your frames arrive safe and are easy to store. Add a microfiber cloth to your routine to keep lenses clean and the frame finish looking fresh between wears.
How do demo lenses work with prescriptions?
Frames arrive with non-prescription demo lenses so fit and alignment are preserved in transit. Bring the frames to your optician, who will replace the demos with your Rx lenses. This makes swaps quick and helps ensure the final lenses sit correctly for clear, comfortable vision.
Are spring hinges on every Cosette style?
Not every frame uses spring hinges. Some styles feature standard hinges, while others add springs for extra flexibility. Check the “Frame Specifications” on each product page to confirm. If you value easy on-off comfort, prioritize spring-hinge models for everyday wear.
What are the color options like - tortoise, blush crystal, purple?
You’ll find versatile classics like tortoise, airy blush crystal, and bold purple accents. Tortoise adds warmth and depth; blush crystal feels light and modern; darker tones read sharp and graphic. Choose a tone that complements your wardrobe basics for effortless daily pairing.
