Must-have autumn pieces from Sézane, Reformation, and more

A fresh roundup of autumn wardrobe essentials, from cozy sweaters to sleek coats and versatile bags.

Must-have autumn pieces from Sézane, Reformation, and more

When the first chill of autumn settles in, the wardrobe instantly calls for pieces that blend comfort with style. This season, Parisian label Sézane has unleashed a new fall lineup that pairs classic tailoring with unexpected color play. At the same time, editors from leading fashion outlets have compiled a selection of high-street and designer finds that echo the same spirit of relaxed elegance. Below you’ll find a curated guide that stitches together these offerings, giving you a clear roadmap for building a capsule that works from boardroom meetings to weekend strolls.

Signature Sézane staples for the cooler months

Sézane embraces the seasonal shift with a mix of stripe-rich shirts, cozy knits, and architecturally cut outerwear. The brand’s striped henley, rendered in cotton, offers a buttery soft feel and comes in a spectrum that includes a muted brown-cream pair, perfect for pairing with denim or tailored trousers. Their cardigan, finished in a subtle cable-knit at the cuffs, adds texture without bulk, while an oversized crewneck sweater—available in six saturated hues—provides a statement-making yet wearable silhouette.

Outerwear receives a sophisticated upgrade. The iconic trench, now spotted on streets from New York to Paris, appears in a refined Arnaud version featuring a stand-up collar and snap buttons for a modern twist. For those craving a more tactile experience, the chore jacket is offered in three materials—cotton, leather, and a houndstooth wool blend—allowing you to match fabric to function. A navy wool coat, draped like a blanket, delivers warmth without sacrificing line, and a sleek leather satchel, though pricey, showcases the brand’s commitment to timeless accessory design.

Editor-approved pieces from other coveted brands

The editorial lens expands beyond Sézane, highlighting pieces that complement the French aesthetic while adding global flair. Jigsaw’s super-maxi wool coat, for instance, provides runway drama in a more accessible price bracket, while The White Company’s alpaca-blend V-neck jumper offers a fluffy, weather-ready layer that pairs effortlessly with jeans. Free People’s embellished duster, reminiscent of vintage glam, works beautifully over a maxi dress and leather boots, delivering a look that feels both bohemian and refined.

Accessories receive equal attention. Toteme’s medium-sized suede tote in espresso delivers a polished silhouette that transitions from office to market errands. Reformation’s oversized cashmere scoop-neck invites you to ditch ill-fitting knitwear, while M&S corduroy barrel-leg trousers introduce textural depth to classic denim ensembles. For footwear, Agolde’s mid-rise straight-leg jeans and Saint Laurent’s suede sneakers provide a sleek foundation for any autumn outfit, and the soft loafers from Sézane—described as “extremely supple”—promise all-day comfort.

Putting it all together: styling tips for the season

To maximize the utility of these selections, think in layers. Start with a lightweight cotton henley topped by a cable-knit cardigan then add a stand-up-collar coat for structure. Pairing a neutral sweater—such as Sézane’s green oversized jumper—with dark denim creates a base that lets statement accessories, like Toteme’s suede tote or a silk scarf, shine. For work-centric days, the wool houndstooth chore jacket combined with tailored trousers and low-profile loafers maintains professionalism while hinting at personal style.

Weekend outings call for relaxed yet polished pieces. Slip into the free-spirit duster coat over a simple tee, tuck into the corduroy barrel-leg pants, and finish with suede sneakers for an effortlessly cool vibe. When temperature drops further, the navy wool coat becomes the go-to outer layer, while the alpaca V-neck knits serve as cosy mid-layers that can be removed as the day warms. Don’t forget the finishing touches: a silk scarf knotted around the neck can transform a plain trench into a statement piece, and a structured leather bag keeps essentials organized without compromising style.

Ultimately, the goal is to build a versatile wardrobe that feels cohesive yet allows individual expression. By mixing Sézane’s Parisian elegance with the eclectic choices from Reformation, Jigsaw, and other curated brands, you’ll own a collection that transitions smoothly from office corridors to cobblestone streets, ensuring you look polished, comfortable, and ready for whatever autumn throws your way.
