Hair style 
In order to look taller, a hairstyle should be thin at the sides and higher up top, which can make you appear as much as an inch taller. Do not have any wide hairstyle.
Clothes
• Avoid clothes with horizontal lines or clothes with a tartan or checked pattern. Avoid cuffs that make your legs appear shorter.
• Vertical lines or stripping make a person appear thinner, and thinness in turn gives impression of more height and makes you look tall.
• Wear shoes that will make you look taller. If you are a female, this should be easy since you can find a lot of shoes with 2 or 3 inches’ heels. For males, wear shoes with thick soles to add more height.
• Avoid clothes that are made from heavy and bulky fabric. They add width and hence shorten the image visually.
• Wear cuffless pants to make the legs look longer and hence making you look taller.
• Wear a coat or jacket that is of the correct length. They should end where the buttocks meet the legs.
