Foundations - ss26 part one

Thoughtful design and subtle, understated detail are the founding principles of Sideline. Our simple goal is to create clothing that is relaxed and feminine, designed to be worn, returned to, and loved again and again. Each season, we revisit those foundations, continuing our commitment to making collections that reflect our belief that fashion can be done differently.

The clothes we wear are the foundation of how we start our day. Dressing is an act that informs who we are and how we feel. We aspire for our clothes to be the foundations of your wardrobe; the steady ground you stand on: practical, effortless, and designed for the beautiful reality of everyday life. Likewise, the fabrics we choose—the tactile nature of the cloth—are the foundations of our design process. Every detail, every silhouette, is a natural extension of its material; pieces born from the loom, designed with care, and crafted to make you feel both comfortable and cherished.

We find a deeper beauty in the signs of wear. A cornerstone of our design philosophy is that each collection transcends its season. These garments are designed to age with you. A well-loved hem or a softened weave becomes a map of your history, telling the story of a day, a year, a decade’s wear. We’re proud to wear last season’s clothes, and we design with this in mind.

Our foundations are our strength. This collection is a celebration of that grounding: simple, thoughtful pieces for the everyday—fabric-led design, built to last.
