Suzette Shift Dress by Maeve sold at Anthropologie
Description from the website:
The name "Maeve" references a purple flower, a Greek goddess and
a¿famously beautiful Irish warrior queen. In light of these
inspirations, it's no surprise that the Maeve brand is both feminine and
playful, a representation of beauty and strength at once. With just a
kiss of glinted thread, this hopelessly romantic jacquard shift is the
quintessential date-night frock.
