People with short hair can style it differently by using products like hair spray or gel to create a more elaborate “do” than usual, or could shave their head completely. Also consider a dye-job, or using cheap talcum powder to make some gray streaks that will really throw people. People with longer hair can consider getting a realistic-looking wig or extensions to change the basic shape of their hair. You can also quickly go back to your “old” style that way, if you want to for further disguises. Keep them guessing by changing frequently and without warning. Dye your hair a different color each week and ensure that you’ll never be noticed. Try combinations of highlight patterns and full dye jobs. If you have facial hair, shave it into a different shape or get rid of it completely. If you don’t have any, consider growing a beard or a sneaky mustache.

If you have contacts, consider trying color-change contacts, or digging out those old frames you no longer wear.

Even if you don’t normally wear make-up, a little can go a long way in changing your appearance. Just adding some eyeliner and changing your clothes can give you a whole different aura.

Consider dressing up or dressing down in age. If you usually dress like a 19 year old, consider how your father dresses and start taking cues from him. Wear polo shirts tucked into khaki pants with your cellphone on a belt clip and you’ll age 20 years in a minute. You could consider dressing in a more masculine or feminine style, for example wearing pants where you might normally wear skirts as a way of changing your general presence. If people are used to seeing you in make-up and nice clothes, it’d be a surprise to suddenly be wearing a basketball jersey.

Try wearing darker colored clothes to appear smaller and hide your natural physique.

Keep make-up and emergency hair dye on your person for a quick transformation. Shoe polish can work in a pinch.

You can even consider working an accent into your disguise. Practice while you’re by yourself and only speak in that accent in public. Change your accents periodically with different people to keep them guessing.

Putting a pebble into your shoe is uncomfortable, but if you’re committed to disguising yourself, it can be a good way to ensure that you’ll walk differently. Brace your knee with a brace to give yourself a natural limp.
