Ami de Coeur T-Shirt Fit Guide: Sizing and Styling Tips

Quick answer

Ami de Coeur T-shirts are not one fit: the black cotton jersey style is cut fitted, the green kids' style is boxy, and the grey sweatshirt is a classic cut. Choose the fitted black tee for a sharp, tucked-in look, the boxy kids' tee for a relaxed shape, and the classic grey sweatshirt for an easy mid-layer. Always check the product page's cut label before ordering, because the same Ami de Coeur embroidery appears across all three.

The three Ami de Coeur cuts, side by side

Ami Paris labels each garment with a specific cut, and that label matters more than the size number. The black Ami de Coeur short-sleeve tee is described as 'T-shirt ajusté' — fitted — in a lightweight cotton jersey. The green kids' tee is 'Coupe boxy' — boxy — with a round neck. The grey Ami de Coeur sweatshirt is 'Coupe classique' — classic — with a round neck. Three different silhouettes, three different sizing experiences.

Because the embroidery is consistent across the line, the cut is the only variable you need to solve for. If you already own one Ami de Coeur piece, match the cut label first, then use your usual size as a starting point.

• Fitted (black tee): follows the body; size up if you want breathing room.
• Boxy (green kids' tee): wider through the chest and shorter in the body; true to size for the intended relaxed look.
• Classic (grey sweatshirt): standard straight cut; true to size for most wearers.

How to read the size chart for each cut

Ami Paris does not publish a single universal size chart across all Ami de Coeur pieces because the cuts differ. The practical approach: open the specific product page, find the cut label in the description, and compare the listed measurements against a T-shirt or sweatshirt you already like. If the page does not list flat measurements, treat the cut label as your primary signal and the size as secondary.

For the fitted black tee, the chest measurement is the tightest constraint — if you are between sizes and prefer a clean line, stay true to size; if you prefer a relaxed drape, size up. For the boxy green kids' tee, the body length runs shorter than the chest width, so taller children may want to size up for length even if the chest already fits. For the classic grey sweatshirt, the straight cut means your usual size should work unless you plan to layer it over a thick shirt.

Styling each cut without fighting the fit

The fitted black Ami de Coeur tee works best as a base layer: tuck it into high-waisted trousers or wear it under an open overshirt, and let the white-cream chest embroidery be the only visible detail. The boxy green kids' tee is designed to sit away from the body, so pair it with slim or straight bottoms to balance the volume — avoid wide-leg pants unless you want a fully oversized silhouette. The classic grey sweatshirt is the easiest of the three: wear it over a collared shirt with the collar showing, or alone with jeans and the Ami embroidery doing the work.

One detail worth noting across all three: the tonal Ami embroidery under the back neckline. It is subtle by design, so if you plan to wear the garment open or with a low back neckline, that detail will show — which is a nice touch, not a flaw.

What the materials tell you about fit over time

All three Ami de Coeur pieces are made from organic cotton and produced in Portugal. The black tee uses a lightweight jersey, which has more natural stretch and will follow your shape more closely after a few wears. The grey sweatshirt and the green kids' tee use heavier cotton constructions, which hold their cut better but also shrink less predictably if washed hot. Wash cold and lay flat to dry if you want the original fit to last.

Because the black tee is lightweight, it is the most forgiving if you are between sizes — it will relax slightly. The boxy green tee and the classic grey sweatshirt are less forgiving, so get the size right the first time.

Decision rules for choosing your Ami de Coeur size

• If you want a fitted, clean silhouette: Choose the black Ami de Coeur short-sleeve tee in your usual size. If you are between sizes and prefer a little room, size up — the lightweight jersey will relax slightly with wear. Best for tucking in or wearing under an overshirt.
• If you want a relaxed, boxy shape: Choose the green kids' boxy tee or the boxy zip sweatshirt. Stay true to size for the intended oversized look; size up only if you need extra body length. Best for casual, volume-balanced outfits with slim or straight bottoms.
• If you want a dependable everyday fit: Choose the grey classic-cut sweatshirt in your usual size. The straight cut is the least likely to surprise you, and it layers well over a collared shirt. Best for a first Ami de Coeur purchase or a mid-layer.
• If you are buying for a child: The green tee is a kids' unisex boxy cut. Check the body length against the child's height, not just the chest measurement, because boxy cuts run shorter. Size up for length if the child is tall for their age.

Ami de Coeur pieces in this guide

• T-shirt Noir Ami De Coeur Court en Coton: T-shirt ajusté in lightweight cotton jersey with white-cream Ami de Coeur chest embroidery and tonal Ami embroidery under the back neckline. The fitted cut makes this the best choice for layering or a sharp, tucked-in look; size up if you want a relaxed drape.
• T-shirt vert en coton Ami de Coeur: Kids' unisex boxy cut with round neck, contrasting Ami de Coeur chest embroidery, and tonal Ami embroidery under the back neckline. The boxy shape runs wider through the chest and shorter in the body, so taller children may need to size up for length.
• Sweatshirt gris en coton Ami de Coeur: Classic cut with round neck, contrasting Ami de Coeur chest embroidery, and tonal Ami embroidery under the back neckline. The straight classic cut is the most predictable fit across body types and works well as a mid-layer.
• Sweatshirt noir zippé en coton Ami de Coeur embossé: Unisex boxy cut zip sweatshirt with engraved 'Ami' zipper pull, raglan sleeves, and embossed Ami de Coeur on the chest. The boxy cut and raglan sleeves give a roomier shoulder fit than the classic grey sweatshirt, so consider your layering plans before choosing a size.
