[1][2][3] Influenced by Pop art, Aguiar held her first solo exhibition in 1973, at Galeria Alvarez in Porto.
Sex became a constant theme in her work, even before the 1974 Carnation Revolution that overthrew the Estado Novo dictatorship and ended censorship.
She created a controversial series of works entitled Marcas, which addressed gender issues and the power relations inscribed in biological bodies.
[1][2][3][4] Aguiar's work has appeared in major thematic exhibitions, most recently in a 2021 exhibition of Portuguese female artists at the Calouste Gulbenkian Museum, entitled Tudo o que eu quero (All that I want), which was part of the cultural programme of the Portuguese Presidency of the Council of the European Union.
Her art is held by various important Portuguese collections, including that of the Calouste Gulbenkian Foundation, the Caixa Geral de Depósitos bank, the Soares dos Reis National Museum in Porto and the Secretary of State for Culture.
