With summer winding down and fall on the horizon, style mavens have reached a familiar and conflicting fashion impasse. On one hand, you want to hold on to your favourite sunny day looks, but you're also openly coveting the always-enticing options from the autumn collections. The solution to this conundrum is mixing and matching older pieces with newer items, resulting in creative and noteworthy outfits that make this seasonal transition a challenge that's actually fun. And although we're sure you're well-prepared for this in-flux time, we also understand that even the most adept dressers can use a bit of inspiration now and then, which is where today's edition of What Was She Wearing: Answers! comes in. From Ashley Olsen's nautical look to Rosie Huntington Whiteley's easy incorporation of leather pants into a daytime ensemble, we have ideas to spare, including ways to reinvent the looks for yourself!

1. Rosie Huntington-Whiteley
We recently highlighted Rosie Huntington-Whiteley's keen fashion sense in our Style Spotlight series, and we're thrilled to find you're just as enamoured with the gorgeous blonde as we are! The model/actress arrived at LAX last month looking decidedly cool in Simone by Katie Nehra's lust-worthy Quilted Leather Pants ($1058), which she offset with a bevy of neutral pieces, including an oatmeal v-neck sweater and a ladylike, nude handbag (both by Burberry Prorsum), as well as a pair of pretty Chloe ballet flats. If Huntington-Whiteley's covetable airport attire seems just beyond your reach, have no fear! Simple options like J. Crew's Cashmere V-Neck Sweater ($168) teamed with Zucko's Faux-Leather Pants ($172) will ensure an equally pleasing result. All you need are Report's Grover Flats ($70) or R2's Grant Flats ($45), and you'll be ready for a first-class flight.

2. Emma Roberts
Starlet Emma Roberts has been on our radar for years now due to her awesome ensembles both on and off the red carpet. The actress was spotted looking incredibly together while out in Los Angeles late last month, once again proving that she has style in spades! Roberts added a ladylike twist to her One Teaspoon Cutoff shorts by pairing them with a lace-lined Miu Miu sweater and Chanel espadrille flats. She accessorized her casual daytime look with Rebecca Minkoff's Endless Love Tote ($250) and a pair of always-on-point Tom Ford sunnies. If you're in want of Roberts' street-ready outfit, start with Madewell's Sweatshirt Sweater ($68), and then throw on a pair of perfectly destroyed denim shorts, like Free People's Denim Cutoff Shorts ($68) or American Eagle's Destroyed Denim Bermuda Shorts ($30). Last, but not least, you'll want to add a pair of girly espadrille flats-ALDO's Sarraga Slip-On Shoes ($20) or Soludos' Dali Espadrille Flats ($26) should do the trick-and toss Kimichi Blue's Striped Straw Tote Bag ($13) over your shoulder, and voil�! You'll be channeling Robert's stylish sensibilities in no time.

3. Ashley Olsen
Ashley Olsen has a knack for putting together effortlessly-chic looks, which is probably one of the reasons you fell hard for her recent daytime ensemble! The fashion mogul was spotted out and about in Manhattan last month wearing a classic nautical-inspired Junya Watanabe boatneck tee coupled with vintage, high-waisted jeans. She finished the look with The Row's Leather Shoulder Bag ($3,900, available here in black) and a pair of Birkenstock's Birko-Flor Gizeh Sandals ($80). To make this look your own, try pairing a similar nautical-inspired top, like Saint James' Meridien II T-Shirt ($95) or Enza Costa's Long Sleeve Sailor Shirt ($127), with a pair of classic, slim denim jeans-we love Levi's Classic Slight Curve Straight Jeans ($50) and Blank's Ankle Skinny Jeans ($78). Round out your outfit with a streamlined satchel like Hera's Business Shoulder Bag ($525), and you'll be turning heads with ease!

4. Selma Blair
Fashion plate Selma Blair is never one to disappoint in the outfit arena, and her super cute maternity styling has proved to be no exception! For example, Blair was photographed enjoying a sunny day in Los Angeles earlier this summer wearing a whimsical white lace Topshop dress. We especially love the way she added a pleasing pop of colour to her breezy ensemble with a pair of Theodora & Callum Pink Ikat Linen Biarritz Espadrilles ($395), resulting in a swoon-worthy warm weather look. To achieve a similar feminine look, opt for a delicate lace dress-Lucky Brand's Olivia Dress ($90), Pins and Needles' Lace Dress ($79), and Imitation's Kiki Lace Tunic ($280) are all fabulous options-and punch it up with a pair of playful pink sandals, like Nine West's Jaxson Slingback Espadrille Wedges ($56).

5. Miranda Kerr
On the runway and in front of the camera, model Miranda Kerr always looks impeccable, and as today's ensemble proves, her off-duty moments are equally memorable. Kerr made quite the style statement last week when she left retailer David Jones in Sydney, wearing Lover's Serpent Lace Dress ($957) in Scarlet and Christian Louboutin's Toutenkaboucle 150 Suede Buckle Sandals ($995). For some show-stopping alternatives, try ASOS' Lace Body-Conscious Dress ($78) or Vero Moda's Lace Dress ($38) with Mark & James by Badgley Mischka's Malana Sandals ($225), and start perfecting your strut!-Calin Van Paris
