Price is firm, no offers please. : ) This is a like new, no tags, authentic Sézane Khalie 100% linen shirt, in a white tone, with large tortoise buttons, & a charming small ruffle at the neck & at the cuffs. Made in Portugal. Does not come with an extra button. I wore this very gently for a few hours, gently washed, & air dried. This blouse runs small—the size of this piece is US6/FR38, but it feels more like a US 2 or 4. I recommend this shirt for an XXS or XS. My usual size is US4/FR36 in Sézane, & I found this piece a too small for me. The fabric content is 100% linen.
