SIDELINE AW26 Drop 1: Shop Now

The shift into early autumn feels that bit sweeter with the arrival of the new Sideline AW26 collection. Known for effortless, everyday wearability, this season’s drop delivers the ultimate transitional wardrobe pieces.

Designed for effortless colder season styling, the collection introduces rich new colours, striped patterns, and folk-inspired embroidery across fresh silhouettes. Loved for over ten years since Sideline’s first-ever collection, the British label's best-selling blouses, dresses, trousers and jackets shapes have been reworked for autumn/winter layering.

Sideline Women's Aida Vest - Brown worn with the Sideline Women's Cloud Hat - Brown


Designed for endless repeat wear, Sideline stays focused on timeless style over fleeting trends. A philosophy that has guided their work since day one - customers who bought from the very first collection a decade ago are still reaching for those same clothes today - for Sideline founder Ellen Brookes, creating long-lasting, trend-proof staples isn't just a selling point; it’s the whole foundation of her brand, and every new season proves it.

New for AW26: The Flo Mohair Knitwear Range

As the seasons begin to turn, transitional layering becomes key. Introducing the Sideline Women's Flo Jumper - Dusky Rose and the Sideline Women's Flo Vest - Plum—two brand-new mohair knitwear additions debuting this season.

Designed to bridge the gap between late summer heat and cool autumn breezes, these knitwear styles pair ultra-soft comfort with responsible manufacturing. Crafted locally in the UK on seam-free, zero-waste machinery, these pieces are spun from premium Italian mohair that feels surprisingly light and airy while delivering cosy, breathable warmth. The classic fisherman's rib stitch adds a tactile texture to both the jumper and vest silhouettes, making them effortlessly easy to style.

Modern Denim Meets Craft-Inspired Detailing

For denim lovers looking for an updated silhouette, the Sideline Women's Ini Patch Jeans - Indigo showcase a modern barrel-leg fit with craft-inspired decorative patchwork detailing.

Sideline Women's Ini Patch Jeans - Indigo


Cut from a robust, deep indigo organic cotton designed to age beautifully over time, these high-waisted jeans offer a flattering, relaxed top block (waistband down through the hips, seat, and crotch) paired with a distinctive curved leg shape. Enhanced by a side panel and knee dart for structure, the design reworks classic 5-pocket styling with an unexpected single patch back pocket and a tonal patchwork detail at the knee. Whether worn full-length or styled with a cuffed hem, they are built to be a long-term fixture in your wardrobe.

We recommend sizing down if you prefer them to feel fitted at the top block.

Investment Wool Outerwear You'll Crave Through Winter

Two absolute favourite styles amongst the Sideline community that we look forward to seeing each autumn/winter, the Sideline Women's Seren Coat - Brown and Sideline Women's Aida Vest - Brown are both made from a beautifully soft, textural brown 100% wool shearling. This natural wool is one we love to snuggle into during colder, dark days - if any encouragement is needed to leave the house, these outerwear pieces will help do it!

Designed with indigo binding linings and minimal fuss and detailing, we love the versatility of these investment pieces, which, with the right care and wear, are sure to last many winters ahead.

The Seren Coat features patch pockets with side entry, a curved collar and button-through front, and is the perfect winter jacket that is both practical and stylish, with a nod to vintage styling and traditional folk style layering.

Cut a little more cropped for AW26 than previous seasons, the reversible Aida Vest looks great layered over knitwear, as an extra cosy mid-layer with jackets or just over your favourite tee.

With its blend of tactile mohair knits, expertly cut denim, and thoughtful, zero-waste craftsmanship, the Sideline AW26 collection proves that seasonal updates don't have to mean throwaway trends. These are versatile, beautifully made pieces designed to carry you effortlessly through the cool months ahead and remain favourites in your wardrobe for years to come.
