Ratanshi has already started in the London-based role and leads a team of three. Her remit includes promoting store openings and product placement. She will also work closely with Patrick Cox himself.
Ratanshi replaces Genny Medeira, who left in October.
Patrick Cox’s estimated sales last year were £40m.
Ratanshi was previously at LA fashion brand Juicy Couture for just under two years as European PR manager. Prior to this she worked at Gucci for five years.
