A recent two-textile collaboration between Designtex and British studio Wallace Sewell — helmed by Harriet Wallace-Jones and Emma Sewell — includes The Thames, a preppy composition of thick stripes, and River Lea, a thinner striated pinstripe.

Inspired by their namesake rivers, both have a finish-free construction and are offered in coordinating colourways (five and six, respectively) that allow for harmonious mixing and matching.
