In 1968, he returned to Italy and began working at his studio in Gregoriana, Rome, where he presented his collections as part of the fashion calendar organized by the Camera Nazionale dell’Alta Moda.

In July 1970, he displayed his work for the first time at the Nymphaeum of the Museo do Arte Etrusca at Villa Giulia in Rome, showcasing looks with models wearing low-heeled boots, without makeup or hairstyling.

He began experimenting with the inclusion of decorative, rigid, and structural elements, juxtaposing "rich" and "poor" materials, such as precious fabrics, stones, and straw.

In 2005, with the Associazione Civita, he founded Fondazione Roberto Capucci to preserve his archive of 439 historical dresses, 500 signed illustrations, 22,000 original drawings, a full press release, an extensive photo, and a media library.

In 2010, he collaborated with artists Maurizio Martusciello and Mattia Casalegno in the audiovisual installation 'Il Gesto Sospeso', commissioned by FENDI and premiered at the Hadrian Temple for the Rome Fashion Week.
