someone with a broader chest or who prefers additional room will want the Large, which adds 6 cm of chest width while only adding 1 cm in garment length.","stonewashed_poplin_hand":"A light stonewash treatment pre-softens the organic cotton poplin before it reaches the buyer, giving it a lived-in hand and a fluid drape that allows the relaxed cut to fall naturally — without this, crisp poplin would hold its shape more stiffly and tend to stand away from the body.","female_model_reference_s":"Garmentory’s female model at 5’9.5” with a 33” bust wears a size Small and achieves a relaxed but not oversized silhouette, confirming that women under around 5’7” or those wanting a closer-to-body fit should choose XS to avoid excess length and width that could read as a dress.","oversized_cut_dimensions":"The chest on a size Medium measures 112 cm (44 inches) and the bottom hem 116 cm, producing a straight, non-tapered cut that hangs away from the body;

after a night's sleep the shirt will show light rumpling rather than severe wrinkling, and the stonewashing softens the visual impact of what creases do form.","unisex_oversized_fit":"The fit is deliberately unisex and oversized, cutting with extra ease through the body so the crisp fabric skims rather than constrains; on most frames, this yields a relaxed, fluid drape that feels louche without looking sloppy.","122_gsm_fabric_weight":"At 122 GSM, the poplin is a lightweight fabric with more body than the 90–110 GSM category often used for diaphanous blouses; on the body, it hangs with a noticeable drape rather than floating, feeling present but still airy.","tight_plain_weave_sheen":"The tightly woven plain weave yields a flat, even surface with a subtle lustrous sheen that catches light — a finish that reads as more polished than standard cotton pyjamas and allows the shirt to double as casual daywear.","extra_long_staple_fibres":"The use of extra-long staple cotton fibres reduces pilling, so the shirt's smooth surface and crisp aesthetic persist through multiple washes;
