What is Sizing Like at Nina Ricci?

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

Nina Ricci sizes small — this is a Parisian luxury house working on French sizing, which typically runs one to two full sizes smaller than standard UK, so if you're usually a UK 12, you'll almost certainly need a 44 or even a 46 here. Getting that conversion right before you spend four figures on a dress is absolutely non-negotiable.

I remember the first time I encountered Nina Ricci sizing properly — I was pulling pieces for a shoot and nearly every sample was labelled a size larger than I expected. The French sizing system has a logic to it once you understand it, but if you go in blind expecting UK consistency, you'll be confused and, frankly, potentially out of pocket. Let me save you that particular headache.

The Nina Ricci Aesthetic — Who Is This Brand For?

Before we get into the numbers, it's worth understanding what Nina Ricci is as a brand, because it informs everything about how the clothes are cut. Founded in Paris in 1932, Nina Ricci is the definition of romantic femininity — think fluid bias-cut silhouettes, delicate lace panels, floaty chiffon, and an almost poetic softness to every garment. This isn't power-dressing territory. It's ultra-feminine, occasion-focused, and undeniably French in its sensibility.

The house has had various creative directors over the decades, but the DNA has remained consistent: clothes that move beautifully, that feel romantic without being fussy, and that are cut with an assumption of a slender, narrow-shouldered frame. That last point matters when it comes to fit — more on that below.

Nina Ricci Size Guide: UK to French Conversion

Nina Ricci uses French/EU sizing throughout. As a general rule, add 8 to your UK size to get your French size — so a UK 10 is a French 38, a UK 12 is a French 40, and so on. However, because the brand cuts for a slim, narrow frame, many women find they need to go one size above even that conversion. Always check the specific measurements against your own.

Nina Ricci's size range is typically FR 34–46 (UK 6–18), though availability at the larger end of the range can be limited in-season. If you're shopping via a multi-brand retailer like Net-a-Porter or Matches, always cross-reference the specific garment's measurements rather than relying on the size label alone — the cut varies considerably between a structured jacket and a floaty silk dress.

How Nina Ricci Fits by Garment Type

Understanding the house's signature silhouettes will help you buy smarter. Here's how the key categories tend to fit in practice:

Dresses: The brand's strongest category and the heart of its identity. Bias-cut and slip-style dresses follow the body closely — if you're fuller through the hip or bust, size up by at least one and consider whether the garment has any give in the fabric. Structured cocktail dresses are cut narrow in the shoulder and straight through the body, which can be problematic for anyone with a fuller bust. Always measure your shoulder width and compare to the garment spec if buying online.
Knitwear & tops: Generally runs true to the French size (i.e. your UK size plus 8), though fine-knit pieces can come up particularly narrow across the back. If you carry width across the shoulders, size up without hesitation.
Tailoring & jackets: Cut slim and structured. The shoulders are cut for a narrow, French frame. I'd advise sizing up by one beyond your standard French conversion here — the jacket can always be nipped in at the waist by a tailor, but let out across the back is much harder.
Trousers: Cut with a slim, straight leg and a relatively high rise. If you have a full seat or thighs, size up. The waistband tends to be fitted — there is very little ease here.
Occasion & eveningwear: This is where Nina Ricci truly shines. The silk and chiffon gowns are exquisite, but they are unforgiving in fit — there's nowhere for excess fabric to hide in bias-cut silk. I cannot stress enough: measure, compare to the garment measurements, and if in doubt, go up a size. You can always have it taken in. You cannot have it let out if there's no seam allowance.

Styling Nina Ricci: A Stylist's Honest Take

Nina Ricci is one of those houses where the clothes genuinely have a point of view — every piece whispers rather than shouts, and that's precisely the appeal. The mistake I see people make is trying to dress it down too aggressively. A Nina Ricci silk dress does not want to be paired with chunky trainers and a denim jacket. It wants barely-there sandals, understated gold jewellery, and the confidence to let the garment do the work.

For daywear, their silk blouses and fluid trousers are incredibly wearable if you lean into the romance of it — a silk blouse tucked loosely into wide-leg trousers with a kitten heel is a deeply elegant, very grown-up look that works brilliantly for lunches, gallery openings, or any occasion where you want to look quietly exceptional rather than obviously fashion.

If you're investing in a Nina Ricci piece, buy the dress. The dresses are where the house's soul lives, and they're the garments that will earn every penny of their cost price per wear.

If You Love Nina Ricci, You'll Also Love These…

Nina Ricci sits firmly in the luxury space, but the romantic, feminine aesthetic it champions is replicated beautifully at a range of price points. Here's where to look:

🛍️ HIGH STREET PICKS

Claudie Pierlot — The most direct spiritual match on the high street. This French brand nails romantic femininity with a Parisian edge — exactly the Nina Ricci world, at a fraction of the price. Sizing uses French conventions, so apply the same size-up logic here.
Cos — For the architectural, understated side of Nina Ricci's appeal. Less romantic florals, more clean lines and quality fabrics. Excellent for the bias-cut and fluid silhouettes. Sizing tends to be European and on the smaller side.
Jigsaw — A thoroughly underrated British brand for feminine, elegant dressing. Their silk and satin occasion pieces punch well above their price point and the fit is reliably true to UK sizing.
Phase Eight — Brilliant for the occasion and eveningwear customer who wants something romantic and polished. Their bias-cut dresses in particular echo the Nina Ricci sensibility remarkably well. Generally runs true to UK size.
Whistles — A go-to for understated, grown-up femininity. Not as overtly romantic as Nina Ricci, but their silk blouses and fluid dresses carry the same quiet confidence. True to UK sizing throughout.
LK Bennett — The natural home of occasion dressing on the British high street. Their evening and occasion dresses are cut with real elegance and their sizing is very consistent. A wardrobe staple for anyone who shops Nina Ricci.
Ted Baker — Known for intricate prints, embellishment and romantic detailing — very much in the Nina Ricci spirit. Their occasionwear is a dependable choice. Sizing runs slightly small, so check the measurements carefully.
Hobbs — For the tailoring and workwear end of the Nina Ricci customer's wardrobe. Beautifully cut, very reliable sizing, and a house that takes fabric quality seriously.

✨ PREMIUM STEP-UP

Maje — Another French contemporary brand that lives in the same aesthetic universe. Feminine prints, fluid fabrics, and a distinctly Parisian point of view. Sizing follows French conventions — size up from your UK.
Reiss — For the occasions when you want Nina Ricci's level of polish in a slightly more structured, British register. Their occasionwear and tailoring is excellent, and sizing is consistent with UK standard (though runs slightly slim in tailoring — size up in jackets).
Me&Em — The intelligent, investment-focused British brand that grown-up Nina Ricci shoppers tend to love for everyday dressing. Cut generously, very reliable sizing, and genuinely wears beautifully.

🌟 LUXURY / DESIGNER ALTERNATIVES

Valentino — The obvious comparison point. Where Nina Ricci is floaty and ethereal, Valentino is romantic with a more dramatic, statement edge. Both share that commitment to femininity as a deeply serious artistic choice. Sizing also runs small — same French/Italian logic applies.
Chloé — The closest thing to Nina Ricci's spirit at a comparable luxury price point. Both brands are rooted in a kind of bohemian Parisian femininity that feels timeless rather than trend-driven. Chloé runs true to French sizing.

🌿 INDEPENDENT PICKS WORTH KNOWING

Needle & Thread — A British independent that has made its name on exquisite embellished occasion and eveningwear at a fraction of the luxury price tag. The romantic, feminine DNA is very much aligned with Nina Ricci. Sizing runs true to UK, which is a very welcome change after all that French conversion maths.
Rixo — The London independent that became a cult favourite for a reason. Their vintage-inspired silk and chiffon dresses are genuinely beautiful and carry that same romantic, movement-focused quality that makes Nina Ricci so special. Sizing is true to UK — and they size up to a 22, which the Parisian houses emphatically do not.
