Argentovivo Project called Piler, they call a Camicie or shirt.  It is a fitted style in a sheer black polyester fabric with a band of black lace under the bust line.  The sleeves are long and sheer, the collar, cuffs and button line is in black satin, the buttons are of mother of pearl with flowers engraved on them.  This is a sexy shirt to be worn with beautiful underwear underneath.  Beautifully cool for the summer.  I love clothing that is so fine it will fit into a tiny bag.   Hand wash, cool.  In a UK Medium/12, an Italian 2, European size 44.  The RRP was £220.00  New and unused in its original box.
