I blame it on the media, and of course those people in the skin whitening industry who advertises big time that being white is beautiful.
Alot of caucasian ladies would love to have brown skin like ours. My mates from work comment on how nice and tanned i am all year round. They do spend loads of money in tanning salon and fake tans and still doesnt look natural/good as ours.
Its the same thing with being thin and having a size 0 dress here. People are obsessed with being so skinny and having cosmetic surgeries.
Its ok to look/feel good however there are certain boundaries.
