Lacoste L3647 vs. L3804B vs. L3803B: Which Kids' Frame Is Right?
All three models—the L3647, L3804B, and L3803B—are built from the same bio-injected acetate and share Lacoste's sporty DNA. The choice comes down to fit, color preferences, and style.
Lacoste L3647: The best all-around option for most kids. With seven color choices including translucent Lumi finishes, the L3647 offers the widest variety. The 50mm lens width fits the broadest age range (roughly 8-14), and the rectangle shape is universally flattering. Starting at $55, it's also the most budget-friendly entry point.
Lacoste L3804B: Choose this if your child loves bold, playful color-blocking and wants something that stands out. The glow-in-the-dark temple arms on select colors are a fun feature that younger kids especially enjoy. The 51mm lens width works better for tweens or kids with slightly larger faces. Expect to pay a bit more ($62.77 starting price).
Lacoste L3803B: Another solid choice at the same $55 starting price as the L3647, with a 51mm lens width. The geometric shape is slightly more angular than the L3647's classic rectangle. If your child has already outgrown 50mm frames or prefers a bit more lens coverage, this is worth considering.
Our take: The L3647 hits the sweet spot for most families. It offers the most color options, fits the widest age range, and starts at the lowest price. The translucent Lumi finishes give it a modern edge that kids appreciate, while the classic rectangle shape reassures parents looking for something that won't look dated in six months. If your child is 12+ or has a larger face, step up to the L3804B or L3803B for the extra millimeter of lens width.
