What is the meaning of the statement all fashion end in excess?

Each new fashion statement must compete with other designers striving to attract attention. This inevitably leads to more and more outrageous or attention-getting devices and designs guaranteed to attract media attention. The excess occurs when designs fail to break through media attention, and ever more startling fashion statements are thrown into the mix in the hope of being "the next big thing". Once a particular cycle is ended, the pattern begins again.
