Sizing conventions vary by brand and by cut — this table shows the standard published conversion. Always check the garment's own size chart when one is available. See how these tables are compiled.
A US 8 women's coat is a UK 10, matching the two-size dress offset — though a coat's own cut adds room for layering underneath, so expect this base size to sit looser than a dress in the equivalent size from the same brand.
Because a coat needs to fit comfortably over a sweater or blazer, some shoppers deliberately size up from this converted number for a structured coat meant to be worn over bulkier layers rather than as a standalone piece.
Frequently asked questions
Should I size up from this conversion for a winter coat?
Worth considering if you plan to wear it over thick layers — coats are already cut with some room for layering, but a heavier jumper underneath can still justify sizing up one from the converted number.
