Yesterday was also the G3 My Little Pony bonanza. If only I didn't hate G3s (21st century before the even-worse TV show version) -- I found more than half dozen between two thrift stores, neither of which were Savers, including one with puffy wings which I assume is G3's answer to Flutter Ponies ("Star Catcher," her name is).
Instead, I bought brand new black leggings on the cheap to wear under dresses when I don't want bare legs but don't want the struggle of tights. Fleece-lined leggings, so not really workable for summer (which is a pity as most of my short dresses are summer dresses), but they do have a nice shiny spandex-y outside.
