^ Oh, no, that's not true. I'm not so familiar with the aspects of clothing throughout the times, but I can say the fabrics used for fashion (which is just as important) have all been influenced somehow by things of the past or other ideas, cultures. Prints for fashion in the 60s was a revival of designs from Victorian times and Art Nouveau, and they were 'modernised' by intensifying the colours and curves to go with the contemporary culture. And as well, prints for fashion in the times of Art Nouveau were inspired, for one thing, by Eastern cultures--that is why there is all this focus on keeping things flat and linear and with sweeping curves, a characteristic in for example Japanese woodblock prints. And also there was a focus on flora, which is seen in Middle Eastern cultures. One of the famous designers in this era, William Morris, had this whole ideal vision of 'bringing back the past' and also often used motifs inspired from art in the Middle Ages. He also had a bunch of other 'revolutionary' ideas, like blockprinting by hand on fabric, etc. By mixing all these ideas together, they just happened to create something fresh. So, you can see it was all a revival then and it was just made to suit the people of their times. Tthis is exactly what a lot of designers are doing in present times. Last year, there was a trend in lace and you can't really pinpoint what period that was really from. Often when people think of lace, they might think of very intricate designs of maybe flowers, but in the Chloé collection, you can see lace designs of flowers so simplified in order to make them 'new' /contemporary. Even for fall '07, I noticed they had dresses of cutwork embroidery, but it was not really cutwork embroidery because they had got rid of all the 'heavy' things--(I'm not really going to go into detail about that) Trends are much deeper than like 'a trend of sixties mod'--You can find some info here on how they develop. I don't have specific links but it's easy to search. Anyway, trend development is much like a science and there is a lot of research on attitudes of consumers and the economy. For one thing, for a few of the recent years, they say people were longing for happier times... and this you might say is what caused the rise in vintage styles. There was also a lot of use in nature-inspired motifs. Plus there is a rise in handcraft...and definitely I can't really link 'handcraft' to another time period. So, the last thing I am going to say is, No one can say that everything has been done before unless they know exactly everything that has been done before.
