New hotel suite in outline (10)
I believe the answer is:
silhouette
'outline' is the definition.
(silhouette is a kind of outline)
'new hotel suite' is the wordplay.
'new' indicates anagramming the letters.
'hotel'+'suite'='hotelsuite'
'hotelsuite' anagrammed gives 'SILHOUETTE'.
'in' is the link.
(Other definitions for silhouette that I've seen before include "Shadowy outline" , "Outline representation" , "image" , "Profile of characters" , "Outline figure" .)
