Like new! Doen poet-sleeve blouse, size S

Like new (I have worn this lovely blouse twice!!) blouse by Doen in a warm-weather blue and cream 100% cotton (poplin?). Collarless, with full poet sleeves and a straight bottom hem. Button-up closure with a three-button cuff. Laid flat, shirt measures 18” across the chest, and is 24” from shoulder to hem. This has less ease than other Doen size small blouses - I am a 34C with broad shoulders so figured out I am a medium in the more fitted styles. Questions welcome!
