AMI Paris Size Guide: Does It Run Large or Small?

It is the question every buyer asks before ordering their first Ami de Cœur piece: does AMI Paris run large, small or true to size? The answer depends on the type of piece — and that is exactly what this guide details, category by category, to help you choose the right size first time.

The general rule: AMI runs true to size, with a generous cut

On the whole, AMI Paris sizes faithfully to French standards: your usual size is almost always the right choice. But the brand deliberately cultivates relaxed cuts, in the spirit of the effortless Parisian wardrobe so dear to Alexandre Mattiussi — we tell the story of this philosophy in the history of AMI Paris. As a result, many pieces have a deliberately loose drape, which should not be confused with a garment that 'runs large'.

Another particularity: a large part of the collections is unisex, designed on a men's size base. If you are a woman buying a unisex piece, take one to two sizes below your usual equivalent, depending on the effect you want.

Jumpers and knitwear: the signature cut, slightly oversized

The Ami de Cœur jumpers — the brand's most sought-after pieces, detailed in our complete guide to Ami de Cœur jumpers and cardigans — have a straight, slightly loose cut: dropped shoulders, a roomy body, elastic ribbing at the cuffs and waist.

Our advice:

• To wear it the way the brand intends (loose, relaxed): take your usual size.
• For a more fitted, close-to-the-body look: go down one size.
• In cashmere, stick to your usual size: the material relaxes slightly with wear.

T-shirts and sweatshirts: loose by design

AMI T-shirts have a boxy (square) cut, wider than classic T-shirts, and the sweatshirts follow the same logic with dropped shoulders. Your usual size gives a controlled streetwear effect; one size down gives a more classic look. If you are torn between two sizes on a T-shirt, take the smaller one.

Jackets, coats and shirts: true to size

On tailored pieces and coats, AMI returns to more structured cuts, true to classic French measurements. Take your usual size, simply checking the shoulder width if you often wear a chunky knit underneath. The shirts have a slightly relaxed cut: your usual size works in almost every case.

Trousers and jeans: watch out for European sizing

AMI trousers are generally offered in French sizes (38, 40, 42…) or in European sizes depending on the model. Cuts range from straight to carrot-fit, and high-rise waists are common. Always check the waist measurement in centimetres rather than relying on the label alone.

The pre-owned reflex: trust the actual measurements

For a pre-owned piece, the official size guide is not enough: a worn piece may have changed slightly, and cuts vary from season to season. That is why every AMI Paris piece sold at NB08 is measured flat: the exact length and width appear on every product page. Simply compare them with a garment you own whose fit suits you — it is the most reliable method there is.

Find all the detailed measurements in our NB08 size guide and the pieces available in the AMI Paris collection — each one checked and authenticated in the boutique, notably through a check of the Ami de Cœur logo. And before buying elsewhere, check the key points in our guide to recognising a genuine AMI Paris piece.

In summary

AMI Paris runs neither large nor small: the brand is true to size, but cuts its knitwear, T-shirts and sweatshirts loose — a style choice, not a sizing flaw. Remember the simple rule: your usual size for the authentic AMI effect, one size down for a fitted look, and for pre-owned pieces, always the flat measurements first.
