Outline changing in hotel suite (10)

I believe the answer is:

silhouette

I'm a little stuck... Click here to teach me more about this clue!

'outline' is the definition.
(I know that silhouette is a type of outline)

'changing in hotel suite' is the wordplay.
'hotel suite' anagrams to 'SILHOUETTE'.
But, I'm unsure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for silhouette that I've seen before include "Profile of characters" , "Outline figure" , "Shadowy outline" , "Outline representation" , "image" .)
