Everything is knitted in our own micro-factory in Hertfordshire, so we know exactly how each piece falls. Here's how to find your size, wherever you're ordering from.
Most GS knitwear is cut with a boxy fit — straight through the body, with room to layer.
Take your usual size. If you prefer a neater fit, take the size down. Where a style is cut differently, we say so on its product page.
Our knitwear is sized S to XXL. Here's how that compares to the sizing you'll know.

Japanese menswear runs smaller than UK sizing — if you're between sizes, take the larger.
Every product page lists that garment's own measurements, taken flat. Silhouettes differ — a cropped cardigan and a sweater vest won't measure the same in a Medium — so it's always worth checking the piece you're buying.
All our measurements are taken with the garment laid flat. The chest figure is half the way round, so double it if you're comparing against something you already own.
Laid flat, measured 2cm below the armhole, from one edge to the other.
From the high shoulder point, next to the collar, straight down to the bottom of the hem.
Find a knit you already like the fit of. Lay it flat, measure its chest the same way, and match that number to the product page.

Japanese sock and shoe sizes are given as foot length in centimetres.

British knitwear is more than craft. It is dedication. It is passion. It is where heritage meets innovation. Genevieve Sweeney began with a desire to preserve an industry from disappearing: the skills, the mills, the hands that make extraordinary knitwear possible in Britain.
Every piece she designs starts with the yarn: natural, responsibly sourced, textural and sumptuous. Colours that evoke emotion, capturing moments in an English garden and the ever-changing tones of the Lake District's rugged landscapes.
From carefully chosen British mills to skilled hands across the UK, each piece is shaped with intention and rooted entirely in British production.
