Does GANNI Run Big or Small? The Ultimate Sizing Guide & What to Buy

GANNI has become a cult favourite for modern women who love Scandi style with attitude—think playful silhouettes, bold prints, and unexpected edge. But if you’ve ever shopped GANNI online or tried to decipher their EU sizing, you might be wondering:

Does GANNI run big or small?
And how do you find your exact GANNI size without trying it on?

In this detailed guide, we break down how GANNI sizing really works, what real customers say, and how Tellar.co.uk can help you get it right first time—with no guesswork and no returns.

GANNI Sizing: Is It Oversized or True to Fit?

One of GANNI’s most recognisable trademarks is its intentionally relaxed silhouettes. But that doesn’t mean every item is oversized. In fact, the brand plays with structure—some garments are slouchy, others are sharply tailored.

What the data says (based on Tellar.co.uk insights):

Tops and dresses: Often run large, especially in styles labelled as oversized
Tailored trousers and blazers: Cut true to size with a modern silhouette
Knitwear and outerwear: Frequently oversized by design
T-shirts and basics: Roomy fit, especially in drop-shoulder designs

Overall Verdict:

GANNI leans large, particularly in dresses, knitwear, and tops. However, fitted styles—especially trousers and structured jackets—run true to size.

Why GANNI Sizing Varies So Much

GANNI’s design philosophy is “playful and effortless”—and sizing reflects that. Their collections are full of variation, which means:

One size 38 could fit like a UK 8 or a UK 12 depending on fabric and silhouette
Oversized cuts are common in knitwear, outerwear, and shirt dresses
Slim trousers and sharp tailoring fit closer to body measurements than most casual items

That’s why Tellar.co.uk is your best bet—it analyses not just the label, but how each category and item type fits.
