Patterns – Clothes with vertical lines will usually make the part of the body they're worn on look thinner. Meanwhile, horizontal stripes will often make that space look wider. Bright, attention grabbing patterns will draw the eye to where they're worn, so if you'd like to emphasize your bust, a patterned shirt is a good strategy. The converse is also true; dark, solid pieces can de-emphasize certain areas of your body, especially when paired with bright patterns.
