Most people would be a little intimated to wear a dress like this. They may not know how to style such a loud piece. But honestly, it is one of easier pieces to style because it does most of the work all on it's own!
Because the dress is so loud it really needs very minimal styling. A nice flat or heel for a dressier look, and small pops of color in accessories are really all you need.
Even in your makeup, like this! A small pop of color in the lip or eye is perfect for this type of piece.
