A late, or adult, neurodivergent diagnosis makes everything clear and messy at the same time. There is so much to unravel, understand and figure out. So yes, it's a huge relief. But also yes. It's complicated.

These are the garment’s own measurements, not body sizes — and one maker’s medium isn’t another’s, so it’s worth a look before you choose. Soft fabrics never cut quite identically, so allow a little either way.
Chest width is measured flat, underarm to underarm — double it for the full way round.
How this one fits
Very smooth and soft. Mid-weight organic cotton, 155gsm. No elastane, so no cling — it holds its own shape. Classic cut, not oversized or cropped. Soft handle, opaque, never heavy.
European fit — slimmer and more structured through the shoulder than a US blank. Square-looking shoulders on a smaller frame are the cut, not a flaw.
Made for you after you order: 1–5 working days to make, then 3–5 to arrive. Free on orders of £85 or more; £3.99 below that. UK and US.
