Wreath or garland for the head (7)
I believe the answer is:
chaplet
I believe this clue is a double definition.
'wreath' is the first definition.
(I know that wreath can be written as chaplet)
'garland for the head' is the second definition.
(I've seen this before)
(Other definitions for chaplet that I've seen before include "flower arrangement" , "Circular garland for the head" , "Ornamental wreath worn on the head" , "Little fellow" , "top band?" .)
