I stumbled upon this frock on eBay and immediately added it to my online shopping basket. I had not seen the dress before and I knew that if I waited, I would not see it again. Perfect for the fourth of July, it screams Americana Fest.
Aside for checking for the historic label, the not-so-secret way of identifying if an item is a Lilly Pulitzer, is finding the label of the iconic namesake within the print of the shift. In the case of this dress, I have found it in three locations in the print, two of which are shown in the above photograph: 1) bottom half of the dress on the far right in red and white with the script running vertical and 2) in the red and white square tile in the middle of the dress just below the collar under the solid blue row of 45 degree squares.
In addition to the items in this post, more vintage Lilly Pulitzer is linked below in a variety of sizes. Always check measurements against the listings and when in doubt, go up a size.
