Festoon

A festoon (from French feston, Italian festone, from a Late Latin festo, originally a festal garland, Latin festum, feast) is a wreath or garland hanging from two points, and in architecture typically a carved ornament depicting conventional arrangement of flowers, foliage or fruit bound together and suspended by ribbons. The motif is sometimes known as a swag when depicting fabric or linen.

In modern English the verb forms, especially "festooned with", are often used very loosely or figuratively to mean having any type of fancy decoration or covering.
