If you always reach for winter puffers, listen up! Kate Middleton just proved that cozy trench coats are this season's biggest trend. She joins other A-listers like Jennifer Garner and Meghan Markle who are swapping bulky parkas for sleek alternatives. While we don't know the exact price of Middleton's Catherine Walker Bespoke coat, this classy lookalike nails the aesthetic - and it's on sale for $68. Like Middleton's choice, this popular Grace Karin coat comes in a sophisticated green hue that contrasts perfectly with neutral color palettes, while also looking festive. It's no wonder the Princess of Wales wore her winter-ready find to a carol service at Westminster Abbey. Additionally, this coat has a slimming A-line fit, a chic double-breasted front and several buttons that give a nod to her royal pick. See it! Skin-soft fabric, gentle pleats and a lapel collar make this on-sale coat the ideal balance of comfy and polished. And with its flattering fit-and-flare design, this coat cinches from every angle to give you an hourglass appearance. The wool-looking material is icing on the cake, making the coat feel elegant and expensive. People will think you spent hundreds! Jennifer Garner Paired a $3,350 Striped Sweater With Sneakers - Shop the Look for $28 The only major difference between Middleton's maxi coat and this twin is the length. Middleton's reaches down to her ankles, however, we actually prefer this knee-length version that will show off your entire outfit. In fact, this timeless outer layer goes well with both casual and fancy ensembles. Middleton wore hers with a tartan skirt and boots, so we're doing the same for date nights and dinner parties. That said, it's equally stunning with jeans, sneakers and an oversized tote bag for school pick-ups and winter travel. Shoppers rave about this stylish find, specifically the warmth, put-together appearance and shaping superpowers. "Super flattering and hides the tummy," one wrote. "I've worn the green one for two years . . . it's still in great shape. I get lots of compliments." Another shared that the coat was warm enough to wear during their winter trip to Germany. "Nice quality. Great tailoring and designed to make me look like I have a waist," they wrote. "The material is the right weight and comfortable, not itchy." See it! If you love the style but prefer neutral tones, you'll find over two dozen color options. It's the easiest way to look like a royal rich mom, even if you're just stepping out for coffee.
