What Is Sizing Like at Gucci?

By Ella Blake — Fashion Stylist | Tellar Fashion Hub — Always honest, unbiased & unsponsored

Gucci runs small — often a full size smaller than UK high street — and if you don't account for that before you buy, you're looking at an expensive return. I've seen it happen to so many people, myself included. Years ago I was gifted a gorgeous Gucci silk blouse in what the label said was "my size," and I genuinely couldn't get it done up. The Italian tailoring is immaculate, but it is cut for a slimmer, narrower frame than most of us are used to from the high street. Once you know this going in, shopping Gucci becomes a lot less stressful — and a lot more enjoyable.

How Does Gucci Size Its Clothing?

Gucci uses Italian (IT) sizing across its womenswear — not UK, not US, not standard European. Italian sizing runs roughly one to two sizes smaller than what you'd expect on the UK high street. So if you're normally a UK 12, don't assume a Gucci IT 42 (which technically correlates to a UK 12) will fit comfortably. The tailoring is cut slim and body-conscious, particularly across the bust and hips, and many UK women find they need to go up a full Italian size to feel properly at ease in the clothes.

Here's how the sizing maps across:

My tip:Always use your largest measurement as the anchor when sizing up at Gucci. If your hips are fuller than your bust, size to your hips. A nipped-in waist is far easier to adjust with a good tailor than a hip seam that won't close.

Tailoring, Dresses & Tops: Expect a Narrower Fit

Gucci's womenswear is built on traditional Italian tailoring principles — beautifully constructed, precise, and designed with a narrower silhouette in mind. The fitted silk blouses, the tailored blazers, the body-skimming dresses — they're all cut with less ease in the bust and hips than you'll find at most premium UK brands. If you're shopping for anything structured, always go up at least one full Italian size from whatever the conversion chart says is "your" size.

Knitwear and more relaxed pieces offer a little more wiggle room, but even then, Gucci doesn't do generous or oversized in the way that, say, a high street brand might. Their knitwear is sculpted and intentional. I'd still suggest going true to your converted Italian size for knitwear rather than going down — you'll be grateful for it.

Gucci Shoes: The Sizing is Genuinely Complicated

Footwear is where Gucci sizing gets particularly interesting, and I say that as someone who has stood in a Gucci boutique genuinely baffled as to why two pairs in the same nominal size felt completely different on my foot. The short version: Gucci shoes are made on Italian lasts which tend to be narrow, and different silhouettes behave very differently.

Horsebit and Brixton loafers — generally true to size but narrow. If you have a wider foot, size up half a size.
Jordaan loafers — these run large, especially the leather versions. Size down half a size, and be prepared for a break-in period as the leather softens and molds to your foot.
Ace sneakers — run large. Most people need to go down a full size from their usual trainer size.
Princetown mules — the fur-lined versions run small; the plain leather tends to run true to size but with a narrow toe box. Gucci themselves suggest going up half a size.
Marmont flat slides — run small. Size up by at least half a size, potentially a full size.
Heels and pumps — generally the most consistent at true to size, though still narrow. If you have wide feet, go up.

My honest advice? If you can, try Gucci shoes in a boutique before committing online. The variation between styles is significant enough that the same foot can be a completely different size depending on the silhouette. If you're buying online, lean towards sizing up rather than down — it's much easier to pad out a slightly-too-big loafer than to wrestle a too-small one onto your foot.

What About the Gucci Size Range?

Gucci's standard womenswear runs from IT 36 to IT 48, which broadly translates to UK 4 to UK 16. Depending on the collection and style, the range can be more limited — some runway pieces only reach IT 44. It's worth noting that Gucci's sizing has historically been criticised for not offering a wider range, though this is something many luxury houses are slowly addressing. If you're above a UK 14 in Italian sizing, your options within the core womenswear collection can be limited, which is genuinely frustrating when you're shopping at this price point.

Is Gucci Worth the Investment?

Genuinely, yes — but only if the fit is right. There is no point spending £800 on a blazer that doesn't sit properly across your shoulders, no matter how beautiful the fabric is. When Gucci fits, it really fits — the quality of construction means the clothes reward the right size in a way that cheaper pieces don't. A well-fitted Gucci blazer or a pair of properly broken-in Horsebit loafers will last years and earn their cost per wear many times over. Get the size wrong and you'll just have an expensive item you never reach for.

Where to Get a Similar Aesthetic for Less

Gucci's signature — that mix of Italian tailoring, bold prints, maximalist detailing and relaxed-but-chic energy — has plenty of more accessible interpreters. Here's where I'd shop across every budget:

High street & premium picks:

Whistles — brilliant for understated, well-cut tailoring and silk blouses that share Gucci's elegance without the eye-watering price tag. Sizing is consistent and generous by comparison.
Massimo Dutti — probably the closest high street equivalent in terms of that sleek Italian-influenced cut. Their tailored trousers and blazers are genuinely excellent, and sizing is more UK-friendly.
Reiss — for sharp, body-conscious suiting and dresses with real structure. A brilliant option when you want that Gucci silhouette without the Gucci price.
Ted Baker — strong for occasion dressing and maximalist prints. Their occasionwear captures some of that Gucci boldness at a very different price point.
Claudie Pierlot — a French brand with real personality. Their printed dresses and tailored separates have a similar eclectic flair to some of Gucci's more playful collections.
All Saints — for the darker, leather-edged side of Gucci's aesthetic. Their leather jackets and suede pieces are superb quality for the price.
LK Bennett — for polished occasion pieces and loafer-style footwear that echoes those iconic Gucci shapes at a fraction of the cost.
Phase Eight — consistently good for print dresses and occasion-ready pieces. Their sizing is genuinely generous and well-labelled, which is a refreshing contrast to Gucci.
Anthropologie — for the eclectic, maximalist, print-heavy Gucci energy. Their occasionwear and knitwear has that same sense of deliberate, considered extravagance.

Two independent brands worth discovering:

Rotate Birger Christensen — a Danish label that absolutely nails the Gucci maximalist party-dressing energy. Bold prints, strong silhouettes, excellent fabrication. If you love what Gucci does for event dressing but the budget doesn't stretch, Rotate is your answer.
Beulah London — a quietly brilliant British label known for beautifully printed silk dresses and tailored pieces with real elegance. Their sizing is consistent and their designs have that same Italian-influenced richness that Gucci does so well. Deeply underrated.
