Stylist Elisa Nalin, before Valentino, Paris, March 2013.
A dress full of Spring flowers: what could be more perfect?! And those spearmint green Valentino slingbacks? Beautiful. 
Recreate Elisa's look (kind of):
Valentino floral-brocade dress, Red Valentino Tropical Landscape organza dress, Suno high neck dress, Cacharel Poplin dress, Alice + Olivia Matilda floral-print dress, Olcay Gulsen round neck dress, Topshop neon floral shoulder dress, Peter Som Burnout damask dress, Ella Moss Citrus flower dress, Moschino Cheap and Chic floral dress, Oasis floral lantern dress, or Topshop Candy stripe Origami dress (not floral but a similar shape to the Valentino dress).
