Ecojilin is a viscose fibre made using pre-consumer cotton linters, a by-product of cotton processing. Developed by Jilin Chemical Fiber, it uses recovered cellulose as the raw material for regenerated viscose fibre. Ecojilin is recognised for incorporating recycled cotton-derived material into the production of viscose.

Tweed is a woven fabric with a textured appearance, often created through the use of different-coloured or textured yarns. It can vary considerably in weight, surface and construction, from relatively smooth and refined fabrics to more substantial, visibly textured ones. Tweed can incorporate woven patterns such as herringbone, checks or other motifs, but these patterns do not define tweed itself. The fabric has strong historical associations with Britain and Ireland and became particularly influential in fashion through Gabrielle Chanel, who adopted tweed for womenswear from the 1920s onwards. Chanel transformed it from a traditionally masculine and practical fabric into a defining material of her fashion vocabulary, most famously in her iconic tweed jackets and suits.

Founded in Paris in 1984 by Evelyne Chetrite, Sandro is known for a distinctly Parisian approach to contemporary fashion. The brand combines understated elegance with sharper, more modern details, drawing inspiration from art, music and the streets of Paris. Sandro later expanded into menswear under the direction of Evelyne's son Ilan Chetrite.
