Sadly, by the time the 1974 Sears Fall-Winter Catalog came out, the miniskirt was officially out of fashion for women. Only the girls section retained its allegiance; the adult section is awash with polyester pants and maxi length skirts.
The Brady Bunch lasted until 1974, and you can definitely see Marcia wearing any of these outfits in the last season.... but Carol had long since moved on to slacks. So, enjoy the pages I've scanned for your viewing pleasure with the full knowledge that, by the '75 catalog, the mini would be history. Like Joni said, "You don't know what you've got till it's gone."
