what is your definition of fashion

i have kin interest in fashion and in my own opinion i think fashion is an art and can go any direction ,mistake can be converted to fashion.....just the way paint or ink mistakenly spilled on fabrics can be taken as pattern

fashion is almost everything around me ranging from hair style , shoes , bracelet , food , internet ,music ,way of life ,architectural design etc
over the years fashion is drastically changing with time , so i can say TIME is a factor of fashion that is, what is in vogue this year might not be next year....example is the green and red pattern of GUCCI is presently trending in fashion,infact some fashion is so extreme,we use waste or mistake as fashion example is using bottle crown as curtain , ripped jeans , tattoo , beards etc

some will prefer clean shave while some will leave full beards as fashion,so different personality with styles
A good desginer should be able to think deeper and out of the box , should be able to make fashion out of anything , yes i mean ANYTHING. thats what makes a good desginer and i bet the sky is the limit for such designer

what is your definition of fashion and your observation about fashion over the years ?
