How was the fashion changed since 1970

In the 70s, fashion truly started becoming more individualistic than before which is a defining aspect of fashion that holds today, but many fads and trends pass in and out. The hippie style was very popular and available to poorer lovers of fashion. Power clothes like women's suits were also in vogue and a well known designer of them would be Karl Lagerfield who is still a popular designer today. Men's clothing stayed consistent throughout the decade with flared collars and pants. Fun dyed fake fur and odd colors were common even will the punk fashion movement started to kick off. 
Unfortunately, many trends of the 70s were considered to be some of the ugliest in present opinions.
The fashion industry itself has no doubt changed drastically with the introduction of celebrity endorsement and social media, but the 70s was one of the first decades of fashion to becoming more like our present fashion industry. 
Popular designers of the decade include: Vivienne Westwood, Diane von Furstenburg, Yves Saint Laurent, and Halston.

Well... lots of things! For one hair styles have changed because women often wore their hair up in complicated styles and wore hats, whereas now people have short shocking styles with dye. The men wore their hair slicked back and often wore a hat as well. There was also a difference of class and therefore rich people wore more expensive clothing materials like silk, poorer people wore cotton. Women wore long dresses and skirts, poor women had simple garments and richer people had plenty of complicated Lacey patterns. Rich men wore suits and poor men wore simple trousers and shirts.

I hope this helps!

Assemblies do not have written codes of laws. laws are matters for magistrates and courts, not assemblies. codes of law are things such as civil law, criminal law, and constitutional law. what assemblies have are procedures regarding debating, voting and other business they might carry out.  also note that rome had three assemblies: the assembly of the soldiers, the assembly of the tribes, and the plebeian councils.
