This might prove that women are a little crazy or we are just really good at planning ahead. My husband never understands why I need to go shopping before we go on vacation and while we are on vacation. According to a new survey from Daily Mail, the average woman spends about $380 on new clothes to take on a trip.  And the average trip costs $1,105.  Which means the new clothes equal about ONE-THIRD of the cost of the vacation itself.
