These Are the Key Ingredients to Fall's Easiest, Trendiest Outfits

Why You Need It: Layer it over a shirt, with a sweater, or rock it as is — this piece is an outfit in itself. And a chic one at that.

Chelsea28 Popover Crop Jumpsuit ($148)

Why You Need It: Statement shoes and jewels will always amp up a simple look, but not as well as a statement shirt. Add something ruffled to a pair of jeans or slacks and automatically your outfit is something special.

One by Stylekeepers Modern Vintage Top ($98)

Why You Need Them: Platforms are in. White sneakers are always in. Pick up a cute combination of the two and rock the sneaker with last Fall's basics. Now your look is right on trend.

Superga Platform Sneakers ($80)

Why You Need It: Cool weather equals layering, and much like a leather jacket can pull any outfit together, a bomber happens to do the same. Even the laziest of jeans-and-tee combos turn stylish with the addition of this It-girl-approved staple.

Factory Stay Cute Try Harder Bomber Jacket ($88)

Why You Need Them: Comfy, trendy, and loved by models? What more could you honestly ask for? Take a styling tip from Bella Hadid and pair your track pants with some heels. Now you look daring instead of supercasual.

Adidas Super Girl Track Pants ($60)

Why You Need Them: It doesn't matter what you've got on, this shoe choice will steal the show. While they'll look great with denim, dare yourself to style them with an oversize shirt and try out the lampshading trend.

Stuart Weitzman Landmark Thigh-High Boots ($785)

Why You Need It: Throw-on-and-go style was the best part of Summer, but it doesn't have to end. Snag yourself a long-sleeved t-shirt dress to style with tights or boots, then be amazed at how quickly you can get ready.

J.Crew Colorblock Stripe Ponte Dress ($88)

Why You Need Them: T-shirts, sweaters, or a polished button-down, these babies will pair well with everything, and that's a very good thing — especially when you're in a rush.

Michael Kors Cropped Printed Stretch-Crepe Culottes ($175)

Why You Need It: It's like your basic button-down but with a hint of flair. Style it the same way you would your favorite collared shirt and immediately look as if you put forth some effort — without doing anything extra.

RED Valentino Cotton Poplin Tie Neck Blouse ($349)

Why You Need It: It's the pop of color your simple outfit craves and it's pretty darn comfy. Win-win!

Monki High Neck Sweatshirt ($49)

Why You Need It: This dress style works for both day and night, depending on your shoe choice and how you layer it. And aside from being versatile? It's easy to shrug on, getting you out of the house in one, two, three.

Asos Sleeveless Chunky Rib Midi Bodycon Dress ($30)

Why You Need Them: They're just as comfy as your favorite boyfriend jeans, but the cropped cut will elongate your leg. Add a pair of boots and a solid shirt and your look is basically done, ready to stand out in the sea of skinnies.

Amo Jane Jean in Recess Wash ($264)

Why You Need It: Just like the bomber jacket, this layer pairs well with everything — even midi and maxi dresses. Throw one on for a quick way to give your look some oomph.

Missguided Long Sleeve Maxi Duster Jacket Grey ($48)
