You might think that height is beyond your control, but by changing the way you dress, you can give yourself the appearance of a couple extra inches.
According to the blog, Grow Taller Secret, if you choose dark and uniform colors, avoid plaids and square designs, wear suit jackets that match your pants, and wear trousers that are long and narrow without cuffs, you'll look taller than you really are.
That said, don't overdo it. The idea with fashion is to choose clothes that suit your appearance. If you're tall, be tall, if you're short and cute, be short and cute. No matter how much money you spend, you're never going to turn yourself into something you're not.
