My Opinion is Purely based on my Observation
Women are naturally more conscious about how they are looking .
They try their best on appearances with the help of cosmetic ,jewelries and type of dresses they have .

Even they take care of matching Sleepers too.I just want to say that ,there are a lot of things whose combined effect vary from one women to another .Basically ,they do so to gain attention of the people and to look different from the crowd .With the emergence in technology ,now they have a good quality selfie phones ,now they have changed to capture all that moments .They take selfie to make them happy and to convince herself that they are looking different ..
