Some supermodel sent back a slipper? (4)
I believe the answer is:
sled
'a slipper?' is the definition.
(something which slips over snow)
'some supermodel sent back' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'back' says the letters should be written backwards.
'dels' can be found hidden inside 'supermodel sent'.
'dels' written backwards gives 'SLED'.
(Other definitions for sled that I've seen before include "Snow transport" , "Toboggan (mainly US)" , "Vehicle on runners" , "Winter transport" , "Tray on which to slide" .)
