As in a trend, yes, it is newer. In general flannel plaid has been around for probably over 100 years. Ild say plaid makes a comeback every 10 years or so.
80's whats his name in pretty in pink totally rocked the red flannel as did the fellow in the breakfast club. I was still playing with my lite bright at this point so I can't really recall.
70's well, every print was in
60's not 100% here
50's and earlier loggers and such was still a happening thing.
