What Is Sizing Like at Vivienne Westwood? A Stylist's Honest Guide

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

Vivienne Westwood runs small — particularly in corseted, structured, and tailored pieces — and if you're shopping this brand for the first time, sizing up by one is almost always the right call. It's one of those labels where knowing your actual measurements matters far more than trusting a label, and getting it right is the difference between a transformative piece and an expensive disappointment.

I'll be honest — the first time I bought Vivienne Westwood I was absolutely convinced I knew my size. I picked up a structured blazer-dress in what I'd usually wear, and when it arrived I couldn't get it done up properly at the waist. The construction is sculpted and unforgiving in the best possible way, but it means you genuinely have to approach her sizing differently to how you'd shop, say, a relaxed contemporary label. Once you understand the logic, though? It all makes perfect sense — and you'll never go back.

Why Vivienne Westwood Sizing Is Different

Vivienne Westwood's entire design philosophy is rooted in historical tailoring — corsetry, boning, sculptural drape, and garments that are engineered to shape the body rather than simply cover it. This is extraordinary when it works, but it does mean that pieces are cut with precision and very little ease built in. The brand uses Italian sizing as its base, which already runs smaller than UK standard, and the structured construction compounds that further in fitted styles.

The other thing worth knowing is that the brand operates across a few distinct lines, each with slightly different sizing approaches:

Vivienne Westwood mainline — the current ready-to-wear collection sold directly and through premium stockists; generally consistent but runs small in tailored pieces
Gold Label (now largely a vintage/archive line) — the couture line; notoriously precise cutting, always size up at least one
Anglomania — the more relaxed ready-to-wear diffusion line; softer fabrics and slightly more generous sizing, closer to standard European sizing

Vivienne Westwood Size Conversion Table

The brand uses Italian sizing. Here's how it maps across to UK, EU, and US:

Important note: Westwood's label conversions have historically printed US sizes incorrectly on garments — IT 38 is marked as US 4, when in reality it aligns closer to a US 2. Always size by the Italian number and cross-reference with your actual measurements rather than trusting the US label conversion.

Sizing by Garment Type

This is where it gets specific, and it's really worth reading carefully before you shop:

Corseted and structured dresses — size up at minimum one, sometimes two. The boned bodice is cut precisely and offers no stretch. These are designed to nip the waist dramatically; if you're between sizes, always go larger
Tailored blazers and jackets — run small through the shoulders and bust. Size up one; the sculptural cut still gives a beautifully fitted result at the larger size
Wrap and draped dresses — these tend to be more forgiving; true to Italian size or one size up if you're fuller in the bust
Knitwear and jersey pieces — the most relaxed fit in the range; these can be true to size or even sized down slightly if you prefer a more sculpted look
Tailored trousers and skirts — check the waist measurement carefully; the waist is narrow in proportion, so even if the hip measurement fits you may need to size up
Shoes — generally true to size; ankle boots and trainers tend to be accurate. Heels can run slightly large; consider a half size down. The Melissa collaboration styles run narrow, so size up if you're a wider fit

Shopping Vivienne Westwood: Practical Tips

Always measure your bust, waist and hips before purchasing — don't rely on what you "usually" wear
For structured pieces, the waist measurement is your key number; these garments are built around it
If shopping vintage or second-hand, ignore the size label entirely and go purely by measurements — Westwood's size conversion has varied across decades
Non-stretch fabrics like taffeta and silk have no give at all, so be even more conservative with sizing in these materials

The Westwood Aesthetic — What to Wear It With

One of the things I love most about Vivienne Westwood is that she built a language of dressing that's entirely her own — and once you understand it, styling her pieces becomes instinctive. The corseted dresses are best worn with minimal accessories; they are the statement. Let the garment lead. For the tailored pieces — oversized tartan blazers, structured jackets — she works brilliantly with wide-leg tailored trousers or a sleek midi skirt. The brand has always had a romance with the unconventional, so don't be afraid to clash prints or mix eras. That's the whole point.

The pearl necklace is the brand's iconic signature accessory and genuinely works across the whole range — from a simple knitwear day look to a full corset dress evening outfit. It's one of those rare accessories that earns its keep.

High Street, Premium and Designer Alternatives to Vivienne Westwood

Westwood's aesthetic — structured tailoring, punk romanticism, statement silhouettes — is deeply specific, but there are brilliant alternatives at every price point:

High Street:

All Saints — the best high street match for Westwood's darker, edgier sensibility; strong on leather, structured tailoring and moody palettes that feel genuinely grown-up
Whistles — excellent for elevated, structured pieces with real tailoring quality; particularly good for blazers and occasion dresses that punch above their price
French Connection — consistently strong on statement bodycon and structured dress silhouettes; a reliable destination if you love the corseted shape without the designer price
Ted Baker — great for the more romantic, feminine end of the Westwood spectrum; occasion dresses with considered construction and interesting fabric choices
Cos — for the architectural, sculptural silhouette in a more minimal register; brilliant tailoring for less, particularly in blazers and wide-leg trousers
Topshop — still delivering via ASOS; historically one of the best high street sources for corset-style tops and structured dresses that nod to the Westwood aesthetic
Massimo Dutti — underrated for tailoring; their structured blazers and wool coats have a genuine quality to them and feel far more expensive than the price suggests
River Island — consistently strong on statement occasion dresses and corset-detail pieces; worth checking every season for affordable takes on sculptural silhouettes

Premium:

Reiss — sharp, elegant tailoring that bridges the gap between high street and designer; their structured blazers and midi dresses have a real sophistication to them
LK Bennett — for the more polished, occasion-ready end of things; excellent construction and beautiful fabrics in statement silhouettes that hold their own

Independent & Niche — Two Labels Worth Knowing:

Preen by Thornton Bregazzi — a London-based label with arguably the closest aesthetic DNA to Vivienne Westwood of any contemporary British designer; punk-informed, romantic, beautifully constructed with a brilliant sense of print. Worth every penny and sizes more consistently than Westwood mainline
Rat & Boa — a British independent label beloved by stylists for its dramatic silhouettes, bold prints and bias-cut dresses; if you love the statement energy of Westwood but want something more accessible and wearable day-to-day, this is the one to know
