Wearing well fitted clothes give you a taller figure.

What you need to do
Choose well fitted clothes and avoid big, baggy, oversized clothes.

Why
Well fitted clothes will show the right body figure proportion, with a short torso and longer legs. With that, your silhouette is stretched upward and you look taller.

However, big, baggy and oversized clothes will make your torso looks massive and legs look shorter, thus making you look shorter than you actually are.
