Wearing an outfit with a monochromatic color scheme will visually trim your figure. Try slipping into a grey A-line dress or a black camisole layered with a black sweater and you'll be surprised by the effect it has on your overall look. Vibrant hues will work too, as long as you don't mind being the center of attention. Bright colors like red and yellow scream "Look at me!", so don't go out for a night on the town expecting to blend in. You should never be bashful about adding a splash of color, though, near your face. It will draw people's eyes up and keep everyone focused on your beautiful smile.
