The movie is getting good reviews, and alot of people are mention the period costumes.
Part of what makes a movie so authentic is the attention to detail. You watch a movie that is set in the 1970's or 1980's and you want to see real cars from the era as well as real clothing. If you don't, then you always have it in the back of your mind that its just not right. That's why period movies are so expensive to make. You have to have the money for the set design as well as the cars and the clothing.
The director who made Silver Lining Playbook is back with another movie featuring the same two leads from that movie: Jennifer Laurence and Bradley Cooper. They are joined by Christian Bale and Amy Adams.
The movie has gotten lots of rave reviews, and many people have said it has one of the best costume designs in recent years. Everything is perfect and fits with the timeperiod. The dresses looked like Halston and other famous looks from the period. You have some disco, as well as some other styles.
The mens costumes are also on the mark. Alot of the time you can say that a mans costume is not really a big consideration. That's true of alot of time periods, since a classic suit always has a similar look, but in the 1970's there were really flashy mens suits. Most people think that these suits are not good looking, but if you are going to make a movie about that time period then you better make it right.
