Gorgeous gowns are best-dressed list staples, so it's arguably more impressive when our favorite celebs are able to turn heads in distinctively dressed-down looks.

This week, it was actress Michelle Williams as well as models Alessandra Ambrosio and Poppy Delevingne who proved yet again that causal and chic aren't mutually exclusive. The ladies stepped out in girly denim, slouchy trousers and shaggy coats that live up to their style star statuses.

Here's a look at the most stylish outfits from the past couple of days. Let us know which outfits you love in the comments section below.

Michelle Williams in Louis Vuitton

This reminds us of the denim jumpers we used to wear as little girls, except Williams' high fashion version is way more chic. The leather belt and darts make the dress flattering on her figure. The patent leather boots add some edge.

Alessandra Ambrosio

Let's face it, models off duty are still models. So it's no surprise that Ambrosio looked amazing even when spotted in between shows at Paris Fashion Week. Her slouchy striped pants are going on the top of our must-have list for spring.

Jessica Alba in Narciso Rodriguez

Monochromatic outfits can run the risk of looking flat (or boring). But that certainly wasn't the case for Alba, who kept things interesting by pairing three shades of pale pink. Her extra long overcoat gave the outfit dimension.

Poppy Delevingne

This is how you successfully play with proportions and texture. The over-sized furry coat works perfectly with the sleek fit-and-flare jeans to create an eye-catching look without much effort.

Solange Knowles in Harbison

Imitation is the sincerest form of flattery. If so, then Solange is applauding her big sis Beyoncé's eye-catching style by wearing the same statement coat that the "Flawless" singer wore while attending the Kanye West x Addias fashion show last month. No need to figure out who wore it best -- both these ladies slayed it.

Dakota Johnson in Christian Dior

It's clear the "Fifty Shades of Grey" actress knows how to turn up the heat. This off-the-shoulder jumpsuit oozes sophistication and sex appeal.

Camilla Belle in Preen

With so much going on -- a busy print, asymmetrical hem and contrast colorblocking -- this dress is definitely a red carpet risk. But Bell pulled off the eye-catching design like a style pro. Her simple strappy heels, white box clutch and side-swept hair add some sophistication to the otherwise wild look.
