When best utilized, accessories alter the mood of an outfit. An addition or substitute of the right accessory can transform your ensemble from day to night. Accessories can convert a tunic dress into formal attire or a cocktail dress into a more casual dress that is suitable to wear to lunch.
One of my favorite, and most functional, accessories is the belt. You only need a couple of belts to accessorize the majority of your wardrobe. A wide black belt and a lighter brown or taupe belt cover a range of styles. It is fun to dig into the back of your closet and try belts on with some of the dresses that you haven't worn in a long time. A belt can quickly modernize a dress and flatter your figure. Best of all, a belt compliments rather than dominates your outfit.
I am in full support of beautiful accessories. I just prefer that the garment is the centerpiece of my look.
