What Is Sizing Like at Norma Kamali?

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

Norma Kamali uses US sizing and generally runs true to size — but because so many of her most iconic pieces are body-conscious jersey styles, the fit is very much about how you want to wear them, and that changes everything. I've been dressing clients in Norma Kamali for years, and the question I get asked most is not "what size am I?" but "should I size up for comfort or stay true to size for that sculpted look?" That's the real conversation with this brand, so let's have it properly.

Who Is Norma Kamali?

If you don't know this name, let me fix that right now. Norma Kamali is a New York-based designer who has been quietly ahead of the curve since the 1970s. She popularised the sleeping bag coat (yes, that one), introduced swimwear as a fashion category, and pioneered the kind of jersey draping that now defines half the dresses you see on a Saturday night. She is a genuine fashion legend — and her pieces have this brilliant quality of looking expensive and feeling incredibly comfortable at the same time. That's not easy to achieve, and she does it consistently.

Her range covers everything from sleek maillot swimsuits and ruched jersey dresses to tailored jumpsuits and outerwear. The aesthetic is body-positive, unfussy, and timeless — she's never been about trends, which is exactly why her pieces never date.

Norma Kamali Size Guide — UK Conversion

The brand sizes in US numeric and letter sizing. Here's your straightforward translation to UK dress sizes:

Quick tip: If you're between sizes, the best approach depends entirely on the style. For structured pieces like the sleeping bag coat, stay true to size. For ruched jersey dresses or bodycon styles, go up one if you want a more relaxed, draped fit — or stay true if you want that sculpted, second-skin effect. More on this below.

Sizing Piece by Piece — What to Expect

Norma Kamali's range is quite varied, and the fit logic really does shift depending on the category. Here's my breakdown:

Ruched jersey dresses — These are the pieces the brand is most famous for, and the stretch jersey is extremely forgiving. I'd say they run true to size but with a lot of give. If you're fuller in the bust or hips, sizing up one gives you a more draped, elegant silhouette rather than a tight one. I tried the Maria dress in my usual size 10 and it was perfect — comfortable but fitted in all the right places.
The Sleeping Bag Coat — An absolute icon and one I've sold to at least a dozen clients. This runs true to size or even slightly generous. It's a quilted, insulated style with a fairly roomy silhouette, so if anything you can size down one and still have plenty of room for layers underneath. Don't be tempted to size up here — you'll just look swamped.
Swimwear & maillots — Norma Kamali's swimwear is remarkable. Her one-piece maillots are particularly good for hourglass and athletic shapes. These tend to run true to size, though women with a larger bust sometimes find the shoulder straps sit better on a size up. The fabric has good stretch recovery — it holds you in without feeling restrictive.
Jumpsuits & bodysuits — True to size, but check the inseam length if you're petite. The cuts are mostly designed for a standard 5'6"–5'8" frame, and if you're under 5'4" the rise can feel uncomfortably long. I always suggest petite clients try these on before committing, or check returns policies carefully when shopping online.
Wrap styles & tunics — Very forgiving. The adjustable ties mean one size often works across a range of bodies. I've seen the same wrap dress look brilliant on a UK 10 and a UK 14 — just worn slightly differently. True to size is always a safe starting point.
Trousers & tailoring — These sit more in line with standard US sizing. True to size, with a clean, slightly wide-leg cut that works particularly well on women who are longer in the body.

A Word on Fabric and Fit Philosophy

What makes Norma Kamali different from most designers is that her pieces are engineered to work with a body, not against it. The jersey styles are genuinely flattering across a wide range of shapes — the ruching disguises and skims in equal measure, depending on where you place it. This isn't accidental. Kamali has always been vocal about designing for real women, and it shows in the cut. You're unlikely to put on a piece and feel like it doesn't work for your shape — it's a brand that tends to make women feel good, which is rarer than it should be.

High Street Alternatives to Norma Kamali

The aesthetic is fluid, jersey-led, and quietly luxurious. These high street picks capture that spirit beautifully at a lower price point:

Anthropologie — Has the same bohemian-meets-polished energy as Norma Kamali. Excellent for ruched, draped jersey styles and midi dresses with that effortless, non-try-hard quality.
& Other Stories — Consistently excellent for Scandi-cool jersey pieces and minimalist wrap styles that echo Kamali's unfussy aesthetic.
Massimo Dutti — Brilliant for the tailored and outerwear side of Kamali's wardrobe. Sophisticated, well-made, and much more affordable than the designer equivalent.
Cos — A natural match for anyone drawn to Kamali's clean, architectural silhouettes. COS does jersey draping really well and their sizing is consistent and easy to navigate.
Phase Eight — Particularly good for the occasionwear crossover — ruched midi dresses and fluid jumpsuits that carry Kamali's DNA without the price tag.
Mint Velvet — Lovely for the grown-up, polished side of Norma Kamali's wardrobe. Soft palettes, fluid fabrics, and styles that look elegant rather than overdressed.
Hobbs — A great pick for Kamali's more tailored pieces. Hobbs does clean, structured womenswear that sits in a similar space — professional, feminine, and with real longevity.
All Saints — If you're drawn to Kamali's more dramatic, sculptural pieces, All Saints has that same darkly glamorous quality at a very accessible price point.

Premium & Designer Alternatives

If Norma Kamali's universe appeals but you want to explore before committing:

Diane von Furstenberg — The wrap dress queen. DVF and Norma Kamali occupy very similar territory — body-positive, jersey-led, and genuinely flattering across a wide range of figures. Sizing is comparable.
Rixo — British premium label doing brilliant fluid, print-led dresses with a relaxed, vintage-inspired spirit. A touch more casual than Kamali but in the same wardrobe conversation.
Me&Em — Polished British brand doing beautifully cut jersey and tailored pieces. Standard UK sizing makes it completely fuss-free to shop.

Two Independent Picks You Should Know

Klements — A London-based independent label making extraordinary printed jersey pieces with real artistry. If you love the fluid, draped quality of Kamali but want something more uniquely British, Klements is your answer.
Rejina Pyo — A Seoul-born, London-based designer whose clean, sculptural silhouettes and thoughtful approach to womenswear puts her in genuinely similar territory to Kamali. Wonderful for investment pieces that feel unlike anything on the high street.

Final Verdict on Norma Kamali Sizing

In short: shop your true US size, which translates neatly to standard UK sizing using the table above. The main variable is how you want each specific piece to fit — and for jersey styles, that's a personal choice between sculpted and draped. When in doubt, go up one in ruched or bodycon styles for a more forgiving fit; stay true to size for outerwear and structured pieces. Either way, you're unlikely to be disappointed — this is a brand that understands the female form in a way very few designers do.
