Empire lines have a great balancing effect.
Any vertical prints or detailing on the top half will flatter the upper body.
Horizontal prints on skirts and trousers will even out your proportions.
Overall prints distribute attention more evenly.
Anything that hangs from the shoulders will have a 'tent' effect.
Wide necklines will widen the look of your bust.
Ruffles, frills or bulky detailing on top will add volume to your upper body.
