How does the sizing of this shirt compare to US/Canadian standard sizes? For example, does a size 36 correspond to a small or extra small?

This shirt uses European sizing, where a size 36 typically corresponds to a US/Canadian small (S). Size 34 is extra small (XS), 38 is medium (M), 40 is large (L), and 42 is extra large (XL).

Is the cotton poplin fabric lightweight and potentially see-through, or is it a heavier weight suitable for wearing without a layer underneath?

The fabric is a lightweight cotton poplin, which is typical for this weave — airy and breathable. However, the specific black and cardamom brown colorway is dark enough that transparency shouldn't be an issue when worn without a layer underneath.

Product Insights

Soeur's Hannah Striped Short-Sleeve Shirt reworks classic men's shirting into a feminine, relaxed piece through a mandarin collar, boxy silhouette, and opaque black/cardamom brown colorway that eliminates the need for an undershirt. The 100% cotton poplin is lightweight, crisp, and durable enough for machine washing, maintaining its low structured drape and subtle horizontal rib texture. European sizes 34–42 map directly to US/Canadian XS–XL (36 equals small), while the back yoke stripe runs horizontally to contrast vertical body stripes, and the three-quarter sleeves offer a moderated length. Soeur's sister founders prioritize opacity and structured detailing—like the chest pocket and the poplin's ability to keep the collar upright—resulting in a piece that balances men's-wear inspiration with feminine ease, though it is currently out of stock.

Deep Research

Soeur's brand philosophy and quality

Soeur (French for 'sister') was launched in 2008 by Domitille and Angélique Brion, and the label's entire identity is built on borrowing from men's wardrobes to create pieces that feel self-assured yet intentionally feminine — this shirt's button-front and vertical stripes reference classic men's shirting, but the rounded neck and soft cardamom-tinted stripes turn it into a distinctly modern everyday essential.

How 100% cotton poplin feels and wears

Thanks to the high number of warp crossover points in the plain weave, poplin has a low, crisp drape that holds the shirt's shape — the rounded hem and straight cut will stand away from the body rather than cling, contributing to the effortlessly put-together silhouette the brand describes.
Poplin is a strong plain weave that withstands repeated machine washing without losing its structure, meaning this shirt can earn a place as a hard-wearing summer staple rather than a delicate once-in-a-while piece.
Poplin is woven as a 1×1 plain weave with fine warp yarns and slightly coarser weft yarns, producing a tight, sleek surface with a minuscule horizontal rib that feels smooth and crisp to the touch — the fabric equivalent of a dress shirt's sharp crease, lending this short-sleeve shirt a pulled-together look even in casual settings.
Poplin shirting typically falls in the 100–140 g/m² weight band, positioning this fabric as a true lightweight that skims the body without adding bulk — a weight class that reads as intentional summer tailoring rather than a concession to heat.
