Everything's from Amazon’s The Drop (and only one piece costs over $100).

Layering is a savvy fashion move year-round, but it feels extra vital come fall. With transitional weather as the standard—and unexpectedly cold or warm days not uncommon—it's the season when being ready for anything can make or break a look.

Enter The Drop, Amazon's influencer-inspired and -led private label that's been making buzzy, of-the-moment pieces affordable since its launch almost four years ago. The current edit abounds with options for wearing over or under pieces already in your closet. For inspiration, browse the round up of styles we'll be reaching for most often this autumn below.

Cardigans are one of the ultimate layering pieces. Wear it open over something filmy, buttoned up and solo, or as part of an entire situation (think: over a tee and under a jacket). Whichever way you're leaning, this grandfatherly version in muted beige will look chic.

Made in a silky lightweight poly-blend, the lingerie-inspired slip dress is intended for steamy nights . . . when worn solo. The juxtaposition against a thick knit, leather jacket, or the aforementioned cardigan is sartorial brilliance.

In recent seasons sweatshirts have stopped feeling like raggedy pajama alts and become standout options on their own. Half-zip styles are still trending up, and this solid colored style can be dressed up or down.

Going for unexpected shapes is one of the more fun, adventurous parts of layering. Pair things that don't go together naturally or look for unique, abbreviated silhouettes. The latter is on display in this quilted anorak, where a familiar style (hooded nylon puffer) meets a cropped hem and short sleeves.

A relaxed waist and swingy silhouette make this sweater invaluable for layering. The forgiving cut, flared sleeves, and back slit help avoid bulk while allowing the cuffs, colors, or ruffles of whatever you might be wearing underneath to peek out.

Dresses don't always leap to mind when you think of fall layers, but there's no reason to leave them out of the mix. A poplin sundress is smart for summer—and brilliant when worn over a starched blouse or sweater. Belt at the waist to create a defined silhouette.

A vest is an intriguing way to play with tailored layers, and this one can be worn basically all twelve months of the year (wear it solo in summer for a sexy take on menswear-inspired styling). For fall, pull it over fine-gauge knits or button-ups, lending a bit of polish without the added weight of blazer sleeves.

A huge roll neck and boxy fit don't overwhelm when the cut is cropped. Pull this find on with high-waisted trousers or jeans or layer over a dress. As with many a piece from The Drop, details are carefully considered: Thumbholes at the ribbed cuffs allow for a sporty-tough look while also offering extra warmth.

A faux fur coat is a stellar outerwear option for fall days where the full bite of winter hasn't quite arrived. (You won't overheat as you might in warmer natural fibers like wool.) Cuddly teddy bear coats are still having their moment, and this chocolate brown pick will look good with almost everything in your closet.
