ISSIMO x F.R.S. For Restless Sleepers. FRS founder Francesca Ruffini is considered l’esempio perfetto of Milanese chic- elegant and stylishly subversive with a touch of boho/radical in a simply pair of luxury pyjamas made from silk fabrics from the finest Como ateliers. ISSIMO x F.R.S. captures the fine details of La Posta Vecchia, Il Mezzatorre and Pellicano.
