Andrea Campagna is a Milanese brand, which specialises in suits and jackets. It was founded by Andrea Campagna several years ago. The brands offers Italian-made pocket squares with machine-rolled edges. They’re made of nice silk and linen fabrics. There are white linen pocket squares with coloured edges and patterned silk squares. Unfortunately, these pocket squares are small – about 32*32 cm. (learn here about perfect pocket square dimensions).
Andrea Campagna pocket squares are available at Barneys New York (New York NY and Beverly Hills CA), Barneys stores in Japan, V Hazelton (Toronto, Canada), TSUM (Moscow, Russia), TSUM-DLT (Saint-Petersburg, Russia). They cost about 60 USD. These pocket squares are usually put on sales twice a year (up to 50% off).
