Over-accessorizing to me is competing with your outfit with your layers and layers of jewelry. Less is more and keep it simple!
Above I styled a statement dress in itself with some accessories to show how to do it right. You never want to layer on bangles and necklaces and steal the show from the statement dress. Since there are square shapes and circles throughout the dress, I chose a pearl multi-strand necklace and a black faceted statement ring to complete this look. Shoe options for this look are a chic pair of black flats or an open toe bootie. The flat is great for day and the open toe bootie great for dinner and a night out.
Do you have any bold statement dresses in your closet? Pull some out for Summer and play around with your accessories and have some fun mixing and matching to see what looks best. Have a good week!
