When you want to start doing something that you are not used to, it is better to consult those who have done it for advice. However, girls can rarely give each other reliable advice on matters beauty as they are in perpetual contest about who is the fairest of them all.
But if girls were not as mean as they are to themselves, they would advise each other on how to put on proper make-up. The kind of things I see being passed as make-up by young women is simply horrendous. The other day, I was in a pub waiting for an exciting football match when two young women walked in.
