They have them today.

My mom wears alot of theses. and so much perfume.

There are always paisley shirts somewhere, but they had peaks in popularity in the late 50s through mid-60s, establishing in the latter era the association with psychedelia that remains today. In the early to mid-80s, we used to haunt thrift shops looking for small-collared early 60s versions. Rarely found any. In 1982/83, the California-based "Paisley Underground" bands were named for their devotion to making music that sounded like it came out of the mid-1960s, and they sometimes wore the paisley shirts were coveted. In the mid-80s, you started seeing paisley prints on the oversized shirts characteristic of the decade. For some reason, my memory is fixing on one that was overly common: an oversized, small-collared shirt with dropped shoulders and long shirttails in back, yellow with small, widely-spaced, grey paisleys scattered evenly all over it. Things like that were so common and so cheaply mass produced that I hated them. But they'd probably be adored by collectors today.

I had a paisley blouse and skirt set.

Wore paisley shirts all the time in the 80s, including an original 60s one. There was a big psychedelic undertow to things then, possibly as a reaction to the blandness of music post- 1982.
