Founded by British designer Ellen Brookes, Sideline is an independent contemporary label built as a direct counter to fast fashion. Characterised by understated detailing, clean cuts, and relaxed silhouettes, Sideline crafts everyday womenswear that feels instantly special yet effortless to wear. At Working Class Heroes, we curate Sideline for its quiet confidence, exceptional fabrications, and alignment with our commitment to long-lasting, utilitarian design.
Thoughtful Design & Subtle Details
Every piece in the Sideline collection is designed with intention. Rather than chasing seasonal trends, the brand focuses on subtle design signatures—custom embroidery, paneled linen, tactile corduroy, and contrast stitching. From relaxed dresses and tailored trousers to versatile outerwear and textured knitwear, Sideline garments are engineered to integrate seamlessly into a functional, modern wardrobe.
Sustainable Fabrications & Ethical Production
Sustainably minded from the ground up, Sideline prioritises natural, low-impact materials like heavy cotton canvas, washed linens, organic denims, and soft wool blends.
- Eco Denim Processing: Denim and casual cottons are finished using innovative laser technology and waterless ozone washing to minimise environmental footprint.
- Traditional Knitwear: Knitted pieces and accessories are produced by established heritage manufacturers in Scotland using seam-free machinery and premium yarns.
- Zero Plastic Packaging: Sideline uses 100% water-soluble, marine-safe packaging, eliminating single-use plastics across their supply chain.
- Ethical Manufacturing: Production takes place in audited facilities that guarantee fair living wages, safe working conditions, and social responsibility.

Frequently Asked Questions
How does Sideline fit compared to standard womenswear?
Sideline typically cuts with a generous, easy-going silhouette. If you prefer a closer, more structured fit, we recommend sizing down one size. If you prefer the intended relaxed, effortless look, stay true to your standard UK size.
Where is Sideline clothing designed and made?
Sideline is designed in the UK by founder Ellen Brookes. Garments are manufactured ethically in small batches by specialist mills and makers in Vietnam, India, and Scotland.
How should I care for my Sideline clothing?
Because Sideline uses natural fabrics like linen, cotton, and wool, wash items on a low-temperature eco cycle (30°C) with mild detergent. Always air dry away from direct heat to protect fabric integrity and custom embroidery detailing.
