Happy National Wear Your Lilly Day (well, yesterday)! I loved wearing my Lilly dress, but the only problem I had was dressing it down. It is a seersucker-type fabric but with polka dots instead of stripes. I have worn it to a few weddings, but I really wanted to try making it a little more casual. One go-to piece of clothing that is able to dress down anything is a denim jacket. And, when paired with some espadrilles, turned my fancy Lilly dress into an everyday outfit.
