100% Italian Linen, Made in Italy
'One-size' fit A. We really dislike this term, but it is how it comes tagged so we can't remove that B. We find, for this dress and depending on your build, it fits approximately sizes 2-10.
Machine wash cold, no bleach, line dry - an iron is safe to use on the fabric, but some love the natural texture of the fabric that comes out when line drying and skip that on by (myself included).
