She was a favorite among high society women from the 1920s to the 1960s for designs that included Jackie Kennedy’s wedding dress. Born in Alabama, she moved to Tampa in 1919 after attending design school in New York City and opened a high-end dress shop. She returned to New York City and opened a shop on Lexington Avenue in 1950 that was an immediate success. Three of Lowe’s Gasparilla gowns are on display at UT. The talk is in Plant Hall, 401 W Kennedy Blvd., Tampa, at 1 p.m. Sunday. 3 Raptor Fest: One of the biggest events of the year at Boyd Hill Nature Preserve brings live raptor birds and free flight demonstrations, bird walks, exhibits with native owls and other species, children’s activities, tram tours, owl pellet dissection, photo ops with birds of prey and crafts. 10 a.m.-4 p.m. Saturday. 1101 Country Club Way S, St. Petersburg.
