Jamie Kay Size Guide: Garment Measurements
Jamie Kay publishes style-specific garment measurements. The Hayes Sweatshirt chart below is an example for that style only, not a body-size chart or a guide to every Jamie Kay piece.
About Jamie Kay sizing
Jamie Kay publishes garment measurements for each style. Allow ± 0.4–0.6 in, as pieces are hand cut. Here is the Hayes Sweatshirt as an example.

How to measure
Use the measurements for the exact Jamie Kay style. Compare the garment length and chest dimension as shown in that style’s chart, ideally against a similar well-fitting garment. Do not use the Hayes Sweatshirt chart for dresses, trousers or every age-labelled size.
