A US 6 dress size is a UK 10 — a US-to-UK dress size typically runs 4 sizes apart, but like all clothing labels, treat this as a starting point rather than an exact match.
UK dress sizes usually sit 4 numbers above the equivalent US size across this chart — a US 0 is a UK 4, a US 6 is a UK 10, a US 14 is a UK 18. This offset is fairly consistent among mainstream UK retailers, though it's still a brand convention rather than a measurement.
Because clothing sizing isn't standardized the way a shoe or bra band is, always sanity-check a converted UK size against the retailer's own measurement chart if it's available, especially for fitted styles where a size up or down changes the fit noticeably.

Clothing sizes are brand-assigned labels, not fixed measurements — use this as a starting point, not a guarantee.
A US 6 is a UK 10.
It’s the most common offset among mainstream retailers in this chart, but individual brands can differ — check the retailer’s own size guide when precision matters.
It’s a reasonable starting point for tops and bottoms too, since US/UK/EU numeric clothing sizes generally track together, but fit still varies by garment style and brand.
