I would like recommendation for old movies which are from 50s & 60s, but you can recommend all the way up to 00s, that are pure eye candy, colorful, even campy, have great fashion, architecture and interiors. The more fun, sparkly and colorful the better :D
Some of the movies that come to my mind are: what a way to go Stepford wives (2004) How to marry a millionare Viva las vegas
