Celine

While running errands in Westwood, Lauren Conrad looked superchic in this olive green Equipment blouse ($216) and these amazing Christian Louboutin black cutout wedges ($1,295). She finished off her streamlined look with not one but two designer bags: a Chanel and her black Balenciaga with rose gold studs. Lauren also showed off her brand-new Céline tortoise round sunglasses, which she recently tweeted about. Add Lauren's exact top and shoes to your Fall mix now to wear together, like she did, or with other standouts in your closet.

As she made her way through the airport in Sydney, Kim Kardashian revealed one of her chicest ensembles yet: a black scoop tank with black-and-white colorblock pants by Australian label Sass & Bide. The reality star accessorized with black flat-top Céline sunglasses, her "Mason Loves Penelope" necklace, a gold watch, black ankle-strap sandals, and a crocodile Hermes tote. Re-create Kim's slick travel style by pairing similar black-and-white pants — we love the Pucci ones below, as well as these by J.Crew ($128) — with a black tank and black statement accessories. Dress them down with flats for day, pumps for work, and sky-high heels for evening.

Kourtney Kardashian walked the streets of Miami with her family looking colorful in her Mara Hoffman printed high-low shirtdress ($368). While we can't take our eyes off of the eclectic tribal print, Kourtney's strategically stylish accessories — nude cat-eye sunglasses, white t-strap Fendi sandals, and a beige Céline luggage tote — are the reason her look is so spotlight-worthy. The reality star wore her dress in a summery way, but we think it would be just as fabulous for Fall. Sport it with tights, booties, and a statement coat, throw on a vest — leather, denim, fur — for further fun, or top it over a black turtleneck for unique styling. Then for some definition in your waist, belt it with a metallic skinny or wide belt.

When Kim Kardashian started dating Kanye West, we noticed that she started dressing way edgier, and her latest NYC ensemble is just another proof of this style hypothesis. Kim paired up a white long-sleeve peplum top with a black leather miniskirt, then finished off with black ankle-strap Celine sandals and a Celine clutch. It's also no secret that Kim has been loving peplums lately. She has a white sleeveless peplum top and even a nude peplum dress. If like Kim you're feeling the minimalist vibe, mimic her latest black-and-white look by matching a white peplum top with a black leather skirt and ankle-strap sandals.

While doing some shopping in West Hollywood with fiancé Jamie Mazur, Alessandra Ambrosio worked a classic black-and-white striped tank with sexy black denim cutoffs, a celebrity-favorite Céline luggage tote, Westward Leaning sunglasses, and her signature Jacquie Aiche horn necklace. But it's her red studded pointy boots that really took her look to rock 'n' roll heights. They're definitely a bold footwear choice and not one that everybody can pull off, but they helped create an even more unique look. Score a similar tank and shorts to pair with red studded boots à la Alessandra, or if that's too out-there for you, pair your stripes and cutoffs with studded sandals instead.

We all know that Miranda Kerr is the queen of stellar street style and the model mom didn't disappoint working a striped tee, suede Isabel Marant high-top sneakers, and these luxurious Linda Farrow python sunglasses ($760) in NYC. Miranda paired her casual topper with true blue skinny jeans, then accessorized with her black Céline bag, multiple necklaces, and a few rings. Re-create her casual-cool ensemble by working a striped tee and skinny jeans with high-top sneakers, then finish off with her exact shades or try these retro snake American Apparel sunglasses ($20) for a budget-friendly version of her wild eyewear.

Miranda Kerr stepped out in NYC, accessorizing her casual-chic ensemble — Céline cropped floral pants and a long-sleeved striped t-shirt — with tortoise Prada cat-eye shades ($245) and her signature burgundy Louis Vuitton duffel ($3,950). The model has proved her love of florals time and time again, but this mixed-print look, complete with nude d'Orsay pumps, stands out for striking the perfect balance between relaxed and chic. Work a striped tee and floral pants to channel Miranda's latest effortless NYC look. Wear it with flats for a day of running errands, then swap the flats for nude pumps for a posterrand dinner.
