My first stop for recreating this look was
ASOS, because they simply have everything. A quick key word search led me to the v-neck black dress, and with some patient page scrolling, I found the sheer plaid blouse (word to the wise, it's a British company so sometimes you have to learn their lingo to maximize your search results - it's checked, not plaid). The shoes are one of my favorite brands, Melissa, via Shopbop. Total cost of my look - $221, that's almost one fifth of the original price of the Marc by Marc Jacobs look!
