I chose other decades since the 70's were the best! Also the 20's had it pretty good as well. Out of the decades you mentioned I'd go with 90's and the grunge look. Today's completely suck. Only good thing is women's legging and hot they show off their butts. Guy's clothes suck since the pants are either to tight or look like you shit yourself in them, and the rest of the cloths look like someone drank too much kool-aid and then threw up on them.
The women and the fashion of the 1940's through the early 1960's, for me. Marylin Monroe, Jean Tierney, Elizabeth Taylor, Greer Garson, Deborah Kerr, Donna Reed, Lauren Bacall, Maureen O'Hara, Audrey Hepburn, etc.
I think besides the insta look or a toned down version, today's fashion and trends are better. No thanks to the shoulder pads, crazy make up, cheap looking clothes (90s and early 2000s, haha), outrageous patterns, and other bad things from other decades.
