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 different numbering base, not just a different offset
EU women's dress sizes use an entirely different numbering convention from the US even-number scale — EU sizes run roughly 32, 34, 36 upward, based on a European continental sizing standard rather than being a shifted version of the US number line. A US 6 landing on a EU 36 isn't an arbitrary two-digit jump; it reflects two genuinely separate historical sizing conventions converging on roughly the same body measurements by different routes.
US sizing has drifted smaller over recent decades through vanity sizing far more than EU sizing has, which means the standard US-to-EU conversion chart represents today's relationship between the two scales, not a fixed physical law — an older US dress, or one from a brand that hasn't drifted as far, can convert to a noticeably different EU size than a very size-inflated modern US fast-fashion label would.
Continental cut assumptions differ from American ones
European dressmaking traditions, particularly French and Italian ones, have historically drafted patterns for a somewhat different assumed body proportion than mainstream US patterns have, often narrower through the waist relative to the bust and hip. A correctly converted EU size can fit accurately in overall garment length and general proportions while still feeling snug through the waist on a fitted style, which is a cut difference rather than a sizing-number error.
What actually helps for an unfamiliar European brand
A fitted continental cut is where a bust/waist/hip cross-check in centimetres earns its keep — a loose, oversized silhouette common in a lot of contemporary European ready-to-wear is forgiving enough that the size-number conversion alone is usually close enough.
European formal-wear sizing runs its own track too
As with US and UK formal wear, European bridal and occasion-wear collections are frequently sized on their own tighter-running scale rather than that brand's everyday ready-to-wear line, so the everyday US-to-EU conversion isn't a safe substitute — bridal specifically is usually made to be taken in or let out by a tailor afterward, and European bridal houses often publish their own separate measurement chart for exactly this reason.
European petite and tall ranges (where they exist at all — they're less universally offered on the continent than in UK or US retail) adjust vertical proportions independently of the girth-based size-number conversion, so converting a US size doesn't automatically tell you which vertical range, if any, a specific European brand offers.
Frequently asked questions
Is a US 6 always a EU 36?
It's the standard published pairing, but since US sizing has drifted through vanity sizing more than EU sizing has, the relationship reflects today's convention rather than a fixed constant — an older or less size-inflated US dress may convert differently.
Why do European dresses sometimes fit snug through the waist even in the 'right' converted size?
Many European dressmaking traditions, especially French and Italian ones, draft patterns for a narrower waist relative to bust and hip than typical US patterns, which can make a correctly converted size feel tighter through the waist on fitted styles.
Does the US-to-EU conversion work the same for loose and fitted dresses?
Not equally reliably — loose, oversized silhouettes are forgiving of small cut differences, while fitted and structured dresses depend more on the underlying pattern block, where US and European traditions diverge more.
Should I trust the size-number conversion for a European brand I've never ordered from?
Treat it as a starting estimate only — compare your own bust, waist, and hip measurements against that specific brand's own chart, since both vanity-sizing drift and cut differences can shift the actual fit.
Can I use the standard conversion for a European bridal gown?
No — European bridal houses typically run their own tighter, separately calibrated size chart distinct from that brand's everyday clothing, and expect tailoring afterward, so check the bridal-specific chart directly.
Do European brands commonly offer petite and tall ranges like US and UK retailers do?
Less universally — petite and tall lines are less standard across continental European ready-to-wear than in UK or US retail, so check whether the specific brand offers one at all before assuming a conversion covers it.
