Jenny Packham Crepe dress with studded collar

Jenny Packham (main line, black label) long crepe dress from a viscose/acetate blend, the dress is in a pencil style with a vent at the back, closes with a concealed back zip and lined in pink satin. Around the neck there are 4 rows of rhinestone and pearls, a bit like an encrusted collar.
Armpit to armpit 46 cm, waist 39 cm, length 140 cm
I would describe the colour as a peachy pink
