Size Guide

Body and flat garment measurements in centimetres for every WFXC jersey style, checked in our Chesham studio.

All WFXC jersey is cut on the same set of blocks in Chesham, so a size M tee and a size M sweatshirt share the same underlying body measurements. Measure yourself in centimetres, then read the flat garment table to see how much room each style carries.

Every WFXC piece is patterned, cut and measured in the same room in Chesham, and each finished garment is checked against the numbers below before it is folded. Our tolerance is 1cm on chest and 1.5cm on length. That means the chart is a promise rather than a guide, and you can buy from the measurements with confidence.

How to measure yourself

Use a soft tape and work in centimetres over light underwear. Keep the tape level and snug but never tight.

  • Bust — around the fullest part of the chest, tape flat across the back.
  • Underbust — directly beneath the bust, where a band would sit. This is the number that matters for support layers.
  • Waist — at the narrowest point, usually just above the navel.
  • Hip — around the fullest part, roughly 20cm below the waist.
  • Back length — from the bone at the base of the neck straight down to where you want the hem to finish.

Choosing between two sizes

Tees, vests and tanks are cut close: the crew neck tee gives you roughly 9-10cm of ease over your bust measurement, so if you are on the join between two sizes and want the fabric to skim rather than cling, take the larger one. Sweatshirts and zip tops already carry 16-22cm of ease, so sizing up mainly adds length and sleeve; take the smaller size unless you want the shoulder seam to sit halfway down your upper arm. Ribbed styles measure much smaller flat because rib stretches — a size M rib tank measures 87cm around the chest and comfortably reaches 104cm on the body.

Support layers

Fit support layers from your underbust measurement first, then check the bust column. Compression styles should feel firm but let you take a full breath; you should be able to slide two fingers under the band. If your underbust and bust point at different sizes, follow the underbust for the zip front and longline styles and the bust for the softer bralette.

Length and height

Our blocks are drawn for a height of 168cm. If you are above 178cm, add roughly 2cm to the length figures in your head — the hem will land higher on you than the photographs suggest, and a size up buys you 1.5cm rather than the 4cm some people expect.
