The American model Kourtney Kardashian turns 42. The Keeping Up With the Kardashians starlet is known for her easy elegant ensembles while juggling being a mother of three children—Mason, Penelope, and Reign—and operating her wellness firm Poosh. Kourtney’s style statement is distinct since she is known for her clever one-liners and wellness advice. We’ve compiled a collection of her most memorable looks.

Here’s the issue about Kourtney Kardashian: out of all of them, she’s perhaps the one we know the least about. The clothes of Kim Kardashian West, Kendall Jenner, and Kylie Jenner seem to produce hundreds of pieces of publicity, seemingly taking over fashion and beauty campaigns and business partnerships all over the world. But why isn’t Kourtney’s style getting the same love? We believe she is currently the best-dressed Kardashian sister.

In the last several years, she’s been gradually changing her style, keeping it glam but with a more mature edge – and we’ve been watching her attentively, very closely. She experimented with figure-hugging tube dresses and leather tops with giant palazzo pants, sweeping robe coats, and tailored jumpsuits, moving away from the OTT Kardashian in-your-face pieces (less leopard print and flashy Birkins).

It whispers demure while she does attractive. She’s also wearing more vintage than ever before, including a Vivienne Westwood corset from last season and an old Céline coat. She has a talent for sprucing up distressed jeans, making cycling shorts work for the evening (pair them with an Acler peplum jacket, high-heeled mules, and a little Vuitton, of course), and always looking ridiculously chic. Damn you, girl.
