Rihanna allows her skirt to be the center of attention by accessorizing with minimalist jewelry. She keeps the look slightly edgy by layering several small statement pieces. The black snapback adds to the casual feel of the overall look.
The best thing about the leather pencil skirt is that you still have the option of dressing it up for a night out. As cooler weather approaches, one could replace the t-shirt with a chunky gray sweater to keep the look casual & polished. Rihanna completed this ensemble with a pair of white pumps for a bit of glam but I could easily see her styling this outfit with strappy heels or sneakers.
