I think a Trend is widely used as a style of a new Vogue that has been launched and given a certain tag name otherwise known as a TREND.
Slowly but surely this Fashion is wide spread to those that have taken a liking to this TREND and will do and buy anything to keep in line with this new in thing and who is in favour of it.
In time the next craze will be out there waiting for followers. There are no time frames as to how long a TREND will last if it will catch on and what thoughts and feelings will surround this newest rage, and what direction it will take.
In life everyone will follow different TRENDS and have the own opinions as what they will wear and what no to wear. Not because something is in Fashion does not mean that everyone will like it.
