You're probably thinking that the pieces identified so far are rather basic. That's where accessories come in. Your accessories are what make your outfit chic and stylish. Think anything from bangle bracelets to designer shoes, a funky handbag to dangly earrings. This is where you get to bring out pops of color and excitement to your outfit.
You can also use your shoes to make a statement. If you're wearing your little black dress with a classic tailored jacket, why not pick up some neon or bright colored flats to spice up the outfit? Or even some fun patterned tights with a pair of trendy boots? Also think about statement jewelry -- bold necklaces or cocktail rings. They go with everything from jeans to skirts.
