First buy cosmetics and accessories. Right makeup will emphasize the dignity of the person and hide weaknesses. Start by applying the usual tonal framework. Choose a shade that best suits your skin tone and apply with sponge or brush.
Secondly, if you want to change your appearance for a theatre or a stage play, clothes play an important role. Forget about high heels. In the cool days dress warmer, do not wear short skirts and short jackets.
Change your hairstyle. This is arguably one of the most important step in the process because stylish hair reflect young age while properly dressed hairs without using any hair colour or dye reflect old age. If you've always had long hair and did not cut them, it's time to make an appointment with the hairdresser. If you do not know what kind of hair style to go for, talk to the hair dresser before trying to seek help from different virtual programs on the internet. There you can not only see yourself with a new hairstyle but also can try unusual makeup and clothes.
Trim your eyebrows if you are a girl. Men can grow moustaches or beard to look older.
To look older, start drinking alcohol and smoking cigarettes or cigars. In this way you will definitely look five to ten years older than your peers.
