How to Style the Lydia Millen Edit: Chapter 3

Some collaborations begin with a collection. The really special ones become a story.

Chapter Three of Lydia Millen x Sinead Keary The Label arrived on 1 October 2026, marking our third edit together and our most personal yet.

Inspired by Sinead and Lydia’s shared love of Autumn Winter dressing, Chapter Three is an eight-piece seasonal capsule bringing together timeless tailoring, luxurious fabrics and beautiful seasonal tones. Satin, cashmere, velvet, wool and soft bamboo come together in pieces designed for autumn days that turn into winter evenings, from work and weekends to dinners and party season.

At the heart of the collection is Evergreen, a new colour created especially for this chapter and named in a nod to Lydia’s book Evergreen. After approximately 140 lab dips, the final shade sits beautifully between a classic evergreen and a softened sage, with a cooler, contemporary undertone.

Alongside Evergreen, rich khaki, black velvet and traditional tartan create a considered Autumn Winter palette designed to work together and alongside the Sinead Keary The Label pieces already in your wardrobe.

Below, discover Chapter Three and how we’ll be styling each piece this season.

What is the Lydia Millen x Sinead Keary edit?

The Lydia Millen x Sinead Keary edit is an ongoing capsule collaboration between Irish designer Sinead Keary and British creator and author Lydia Millen.

Now in its third chapter, the collaboration has evolved season by season, rooted in a shared love of timeless style, beautiful fabrics and considered capsule dressing.

Chapter Three brings the two worlds together more closely than ever. Lydia’s romantic appreciation of the seasons, countryside dressing and timeless English style meets Sinead’s instinct for modern tailoring, flattering silhouettes and effortless glamour.

Familiar Sinead Keary The Label signatures return, but nothing has simply been repeated. Proportions have been reconsidered, details modernised and fabrics and colours evolved to create a capsule that feels familiar yet entirely new.

As Sinead says of the collaboration, Chapter Three isn’t about starting again, it’s about taking something special and allowing it to evolve.

What is in Lydia Millen Chapter Three?

Lydia Millen x Sinead Keary The Label Chapter Three is an eight-piece seasonal capsule, bringing together timeless tailoring, luxurious fabrics and rich autumnal textures. At the heart of the collection is Evergreen, a new signature shade created especially for this chapter, alongside cool-toned khaki, black velvet and traditional tartan.

Designed for Autumn Winter dressing, the edit moves effortlessly from everyday tailoring and luxurious cashmere to evening velvet and soft bamboo sleepwear, with every piece designed to work together and alongside the chapters that came before.

How do you style a longline coat?

A beautifully cut longline coat is one of those forever pieces that anchors an Autumn Winter wardrobe.

The Jessica Longline Wool Coat in Khaki from Sinead Keary The Label is crafted from 100% wool, with a sculpted shoulder and cool-toned khaki shade that sits beautifully between classic khaki and Evergreen.

For an elevated everyday look, layer it over the Lily Cashmere Bow Back Sweater with tailored trousers. For a more tonal approach, introduce Evergreen satin underneath, the subtle contrast between the khaki wool and fluid Evergreen satin creates depth while keeping the palette beautifully considered.

The Jessica is designed to be the coat you return to season after season: timeless, refined and easy to layer over both everyday and occasion looks.

How do you wear Evergreen for evening?

Evergreen was created especially for Chapter Three and is designed to behave almost like a neutral, rich and understated in tailoring, with a beautiful depth and movement when translated into satin.

For evening, we love it worn tonally.

Style the Lydia Wrap Blazer in Evergreen with the Becky Silk Cami and Sandra Satin Trousers in the same shade. The contrast of structured tailoring, pure silk and fluid satin adds texture while keeping the look beautifully cohesive.

The Lydia is the defining piece of the chapter, inspired by seventies glamour with a wide lapel, structured shoulder, signature double cuffs and an oversized removable Obi-inspired belt.

Worn as a complete Evergreen suit, it’s a statement in tonal dressing while still feeling timeless enough to wear season after season.

How do you style the Jennifer Velvet Jacket and Skirt?

The Jennifer Velvet Jacket and Skirt in Black bring a little more glamour to Chapter Three.

Crafted in premium lined cotton velvet, the Jennifer Jacket features a subtle puff shoulder and diamanté trim through the neckline, centre front and cuffs. The skirt follows the fit of our much-loved Lucy, creating a feminine silhouette that feels particularly special for party season.

Wear them together as a full velvet co-ord and let the fabric and diamanté detailing do the talking, or separate the pieces to bring a touch of evening glamour to your existing wardrobe.

Style the jacket over satin trousers and a silk cami for dinner, or soften the skirt with cashmere and a classic heel.

Designed together, but made to be worn far beyond one occasion.

How do you style khaki for Autumn Winter?

Khaki is one of the key supporting shades within Chapter Three, bringing a softer neutral into the collection alongside Evergreen and Black.

The Lily Cashmere Bow Back Sweater is crafted from 100% sustainably sourced cashmere, with softly flared sleeves and a satin bow detail at the back. Wear it with Evergreen Sandra Trousers for Tonal/elevated look, or style with denim when you want to bring a little everyday luxury into your wardrobe.

Layered over it, the Jessica Longline Wool Coat in Khaki creates an effortless tonal pairing.

The beauty of the Chapter Three palette is that Khaki and Evergreen can be worn together as easily as traditional neutrals, giving you new combinations while still working with the pieces already in your wardrobe.

Is the Tartan Sleepwear part of the Lydia Millen edit?

Yes. Tartan Bamboo Sleepwear completes Lydia Millen x Sinead Keary Chapter Three.

Designed in a rich green and navy tartan on our signature soft bamboo jersey, with scalloped detailing, it brings a traditional touch to the collection and a nod to Lydia’s love of Christmas dressing.

Made for cosy evenings, slow Christmas mornings and gifting, it’s a softer final chapter to an edit built around the rituals and moments of Autumn Winter.

How do Chapter Three pieces work with earlier Lydia Millen chapters?

Each Lydia Millen x Sinead Keary chapter has been created with capsule dressing in mind. Familiar Sinead Keary The Label signatures return in new colours, fabrics and finishes, allowing new pieces to sit naturally alongside those from previous edits.

That’s particularly true of Chapter Three. Rather than starting again, the collection evolves the pieces and silhouettes that have become part of both Lydia’s wardrobe and the Sinead Keary woman’s wardrobe.

A favourite coat from an earlier edit can be layered over the new Lily Cashmere. Existing Sandra Satin Trousers can be restyled with the Jennifer Velvet Jacket. And Chapter Three’s Evergreen and Khaki shades introduce a new tonal palette while still working beautifully with the creams, navys, blacks and plums of previous seasons.

It is capsule dressing at its most considered: pieces designed not just for one launch or one season, but to become part of a wardrobe that continues to evolve.
