Beginning of 1970's Research

I have began by looking into some 1970's magazines, and I have taken lots of photographs of the covers, as I think that it sums up how the fashion changes throughout the era, just by how different models are dressed and posed.

I didn't have enough time read and go through all the magazines so I am planning a second trip to really gather some good first hand information however this is what I have looked at to begin with.

I have noticed that the trouser suit if woman is ver strongly apparent throughout the 1970's. I know that this began in the 1960's however it has become very apparent and more worn during the 1970's.
