The IAnn Mashburn Isla Dress is a romantic, slightly oversized shirtdress shape, and this one is made of a super-lightweight, fluid cotton-silk habotai from Italy with a beautifully subtle sheen to it. Don’t let the silk part throw you off… or the cotton part, either, for that matter… we love how the fabric can be dressed way up or way down. Just swap out the shoes and you’re set.
