NWT Sezane Chemise Pierre in Aria Floral Print Button Up Blouse Size tag is 38 but equivalent to a US women's 6. Lightweight silk and cotton blend. Print of shirt varies from stock photo and actual top, as each piece can be unique on the placement of the florals, etc!!! Please reference actual photos I took with measurements (length, sleeve length from neck to end of sleeve, and Armour to Armour), fabric tag. Please ask any questions you may have.
