Saint Laurent SL 28 SLIM vs SL 318 vs SL 28 METAL
If you're drawn to Saint Laurent's Classic collection, you're likely weighing a few square acetate options. Here's how the SL 28 SLIM stacks up against two close relatives in our catalog.
SL 28 SLIM vs SL 318: Size & Profile
The SL 318 offers a larger 56-17-145mm fit with thicker acetate construction, making it a better choice if you have a wider face or prefer more coverage. It's also priced lower ($186–$233) and available with photochromic lenses that adapt to changing light. However, the SL 28 SLIM's refined 49-23-150mm proportions and ultra-thin SLIM profile deliver a lighter, more versatile unisex fit that works across a broader range of face shapes. If you value understated elegance and all-day comfort, the SL 28 SLIM is the more sophisticated pick.
SL 28 SLIM vs SL 28 METAL: Material & Aesthetic
The SL 28 METAL shares the same iconic shape but swaps acetate for metal construction. The metal version feels sleeker and more industrial, with thinner temples and a premium price tag ($384–$398). It's a strong choice if you prefer minimalist, architectural eyewear. That said, the acetate SL 28 SLIM offers warmth, hypoallergenic comfort, and a wider range of color options at a more accessible price. Acetate also ages beautifully and can be polished back to its original finish—something metal can't match.
Our Recommendation
The SL 28 SLIM hits the sweet spot: refined enough for fashion-forward wearers, practical enough for daily prescription use, and priced to deliver Saint Laurent quality without the metal upcharge. It's the frame you'll reach for every day.
