I'm 5'2 how can I make myself taller?

Wear clothes that flatter your body type, many style websites will help you to better understand if you have an hourglass, Apple, or pear figure. Once you know your body type you can find clothes better suited to flattering it. Also, wear clothes that fit, make sure they're comfortable and not too tight. That being said don't hide behind baggy clothes! You don't have to wear a size 0 to be attractive. Just wear what looks good, mix and match to create outfits. I always find that when I wear clothes I like and that look good on me, I'm a lot more confident in myself.
