Beast's loved one strips, turning to bed early for this (6,5)
I believe the answer is:
beauty sleep
'to bed early for this' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for beauty sleep that I've seen before include "Slumber before midnight" , "Shut-eye necessary to remain attractive?" , "to bed early for this" , "What we all need at night to look our best" , "Refreshing rest" .)
