"Cidinho" is the ultimate protagonist of swimwear in South America. He is the inventor of the models "Asa Delta" and "Fio Dental", which went around the world. In 1979, Cidinho opened the first pure swimwear store in South America, in Ipanema, a district of Rio de Janeiro. Shortly after, he founded his own label, "BumBum Ipanema," and transformed his store into a single-brand store, the first of its kind in South America. The brand expanded greatly and had stores in Europe and North America. Today, Cidinho is in his mid-70s and still operates BumBum Ipanema stores around Rio de Janeiro. He is the center of all historical publications about swimwear in Brazil. At the end of 2019, Cidinho celebrated the 40th anniversary of his brand with great publicity. His charisma is spirited and infectious. He is a brand himself and the most positive ambassador for swimwear and the pure pleasure and joy of beach life. Cidinho is a legend for life.
