With her shorter Rachel 'do in full effect, Miley Cyrus got nostalgic while at lunch with a pal in L.A. on Thursday ... by wearing her favorite "Designing Women" blazer, Madonna's "Open Your Heart" bustier and a pair of high-waisted acid wash jeans last seen backstage at a Bon Jovi concert in 1987.

Just like Gaga, the 19-year-old is very fashion forward.
