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.
(silhouette is a kind of outline)

'changing in hotel suite' is the wordplay.
'hotel suite' anagrams to 'SILHOUETTE'.
Though, I'm not clear how this 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" .)
