Mystery

All the colours of the rainbow, what do all these gowns mostly have in common?   The styles vary from the young ingenue/royal fiancée/princess bride to the chic and elegant celebrity princess superstar philanthropist.  They all are mostly worn with a tiara, but not always the same tiara.  Some of them were worn at palaces, some at government buildings, some at hotels.  Beaded, sheer, spangled, pin-tucked, ruched, ruffled, shirred, sheer, embroidered, opaque, gathered, tiered...so many styles and one piece almost always in sight.
