What Is Sizing Like at Iceberg?

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

Iceberg runs small — and if you're shopping as a UK customer without knowing this upfront, you will almost certainly order the wrong size. The brand uses Italian sizing, which is designed for a slimmer, more tailored silhouette than most UK women are used to, and their knitwear and fitted pieces in particular have a habit of catching people out. I've had more than one client come to me baffled because their usual 12 suddenly felt like a 10 had been sewn shut. The golden rule with Iceberg? Size up, at minimum, one full size from your normal UK size — and sometimes two in more fitted styles.

Understanding Italian Sizing — The Root of the Problem

Iceberg is a proudly Italian brand, founded in Bologna in 1974, and it sizes like one. Italian fashion is designed around a lean, narrow silhouette — think less room in the shoulders, a tapered waist, and minimal ease through the hips and chest. This is completely intentional. Italian tailoring philosophy is built on precise, body-skimming fits that look extraordinary on the runway but can feel baffling when you're standing in your living room holding a jumper that looks like it's sized for a teenager.

Here's the practical conversion you need to know:

Italian size 38 = approximately UK 6–8
Italian size 40 = approximately UK 8–10
Italian size 42 = approximately UK 10–12
Italian size 44 = approximately UK 12–14
Italian size 46 = approximately UK 14–16

Notice the gap — Italian sizing doesn't map cleanly onto UK sizes, and Iceberg can sometimes sit between two UK sizes, particularly for women who carry more volume in the bust, hips, or shoulders. In those cases, always err on the larger size. You can tailor down; you can't conjure fabric that isn't there.

Which Iceberg Pieces Are the Most Problematic for Sizing?

Not all Iceberg pieces are equally unforgiving. In my experience, here's what to watch out for:

Graphic knits and jumpers – Iceberg's signature. These are often fitted through the body and have very little stretch. If you're fuller in the bust or have broader shoulders, you'll feel the tightness here first. I'd size up two sizes in knitwear if you're between sizes at all.
Fitted jersey pieces and T-shirts – The branded tees and logo tops are cut slim. They're meant to sit close to the body, which is great if you want that sleek Italian look, but be aware they won't have the relaxed drape of a standard UK high-street tee.
Outerwear and coats – More forgiving than knitwear, but still narrower through the shoulders than UK-cut outerwear. If you're wearing layers underneath, I'd still size up one.
Trousers and jeans – These can vary depending on the line. Some Iceberg trouser styles use a slim European cut with a narrow waist-to-hip ratio, which can be awkward if you carry more on the hips. Always check the waist and hip measurements, not just the size label.
Dresses – The smarter occasion pieces tend to be more structured, with limited stretch. Size up and cinch with a belt if needed — it looks intentional and chic.

Who Does Iceberg Suit Best?

Let's be honest: Iceberg's fit profile does favour slimmer, more straight-up-and-down body shapes — the Italian cut rewards narrow hips and a slim torso. But that doesn't mean it's off-limits if that's not your frame. Here's how I'd approach it by body shape:

Straight and slim figures – Iceberg's sweet spot. The fitted knitwear and slim-cut pieces will sit beautifully.
Hourglass figures – Size for your widest measurement (usually hips or bust). The waist will often have room to spare on a curvier frame, and a quick alteration can solve that.
Pear shapes – Size for your hips, especially in knitwear and anything fitted below the waist. You may find the waist comes up large, but that's a much easier fix than a too-tight hip.
Fuller busts – Be extra cautious with fitted knitwear and any styles with a high or close-cut neckline. Iceberg knits don't have a lot of give across the chest.

Iceberg's Aesthetic — Is It Worth the Sizing Faff?

Genuinely, yes — if bold, graphic, Italian luxury is your thing. Iceberg has been having something of a resurgence under creative director James Long (a British designer, which gives the current collections a slightly more wearable edge for UK women). The brand's signature is its cartoon and pop-culture graphic knits — think bold logos, retro references, and statement outerwear that you absolutely cannot blend into the background in. It's not understated dressing. It's fashion with a capital F.

The quality is excellent — this is Italian craftsmanship, with the price tags to match — and the pieces have a longevity that fast fashion simply can't replicate. A well-chosen Iceberg knit is an investment piece. You just need to make sure you're investing in the right size.

Similar Brands to Iceberg — At Every Price Point

Whether Iceberg's sizing is putting you off, or you simply want to explore the wider world of graphic-led, European-influenced fashion, here are my picks:

High Street & Mid-Market:

Zara – Also runs small with a European fit, so similar sizing caveats apply. But for graphic knitwear and bold seasonal pieces with an Italian-adjacent aesthetic at high-street prices, Zara is the closest comparison. Size up here too.
Mango – Spanish brand with a similarly slim European cut. The graphic jersey pieces and structured knitwear are genuinely very good. Again, size up — and check the measurements on anything fitted.
Cos – More minimalist than Iceberg, but shares that European precision and quality-focused approach. Sizing here can run oversized in some cuts and slim in others — Cos is all about the intentional silhouette.
Massimo Dutti – Part of the Inditex family (same parent as Zara) but elevated in quality and Italian-influenced in aesthetic. Excellent structured knitwear and outerwear with a similar sizing profile to Iceberg. Worth exploring if Iceberg's price point is a stretch.
Hugo Boss – For premium branded fashion with a similarly bold identity and European cut, Hugo Boss is a very strong alternative. The quality is superb, sizing runs slim (as you'd expect from a European designer brand), and the outerwear in particular is exceptional.
Calvin Klein – Clean, American-influenced but European in execution. The logo knitwear and statement jersey pieces are solid alternatives to Iceberg's graphic tees and branded knits, and sizing is more forgiving with a slightly less severe slim cut.
Tommy Hilfiger – Graphic heritage knitwear, bold branding, and a fun, confident aesthetic that shares Iceberg's love of logomania. Sizing is more generous than Italian brands — closer to true-to-size UK.
All Saints – For the edgier, slightly dark-luxury end of Iceberg's aesthetic. Excellent leather pieces and graphic knits with a more British sensibility. Sizing generally runs true to UK size.

Independent Picks:

Sporty & Rich – A genuinely cult American brand that blends luxury sportswear, retro graphics, and a bold visual identity in a way that feels very Iceberg-adjacent. Still relatively under the radar in the UK, which is exactly why I love recommending it. Sizing follows US standards, so check conversions carefully.
Sunnei – An independent Italian label out of Milan doing interesting, graphic, slightly irreverent fashion that shares Iceberg's Italian DNA without the mainstream price tag. Very much a fashion-insider discovery — worth knowing about if you love the Italian luxury sportswear world.
