A floppy white hat and sneakers? You are right, that sounds kind of silly. But it totally works. One of the best ways to create a unique outfit is to take two completely opposite elements and put them together. One of my favorite ways to do this is by mixing ladylike chic clothing with tomboy accessories. Put them together and what do you get? A lot of compliments. See my outfit below for inspiration.
