Should I show personalized product recommendations in cart?

Hey fellow e-commerce entrepreneurs, I've been wrestling with cart optimization for months. My store gets decent traffic, but I'm seeing way too many abandoned carts. I've heard about product recommendations, but I'm skeptical. Will these recommendations actually increase my average order value, or just annoy potential customers? I'm running a fashion brand, and our margins are tight. Every additional sale counts, but I don't want to create visual clutter that might distract customers from completing their purchase. My current checkout process feels sterile—just a basic cart with no personalization. But I'm wondering: Could strategic, intelligent recommendations actually rescue those teetering transactions and turn hesitant browsers into committed buyers? I've seen some recommendation widgets that look spammy, so I'm looking for something sophisticated that feels native to my brand's aesthetic. My ideal solution would understand customer intent, show relevant products without being intrusive, and potentially increase my order value without feeling like a desperate sales pitch. I need data-driven personalization, not just random product suggestions.
