In the US, certainly more women are overweight. The female population is (on average) generally heavier.
Women are now far more likely to have piercings and tatoos than 40 years ago. Shorter hair in young women is now more common but still not the norm.
Women tend to use more natural looking makeup now but emphasize their gender by wearing skimpier clothes.
They are more educated, especially when you remember the minorities you forgot to count in the 70s.
Yeah, there has definitely been an attitude change. Some of it's good, some of it's bad.
Obviously, there is more variety to jobs women have, and women have simply simply taken over some careers. When was the last time you saw a male teller or dental hygienist. Certainly the majority of graduating doctors and lawyers are now female (not true 40 years ago).
At least in the West, Women are, on average, less happy than they were 40 years ago. Despite many feminist protestations, even feminist organizations such as the Huffington Post have reported it (Male happiness hasn't significantly changed).
Although generally (the US is an exception), both genders are living longer, but women are adding to longevity more slowly than men, probably due to an increase in smoking (relative to men), drinking etc. However, they still outlive men by (in the US) 5 years.
