More beautiful female ditched a clothes horse (5)
I believe the answer is:
airer
'a clothes horse' is the definition.
(I've seen this before)
'more beautiful female ditched' is the wordplay.
'more beautiful' becomes 'fairer' ('fair' can be similar in meaning to 'beautiful').
'female' becomes 'f' (abbreviation).
'ditched' suggests deleting specific letters.
'fairer' with 'f' removed is 'AIRER'.
(Other definitions for airer that I've seen before include "Frame for drying clothes" , "I rear (anag) - frame for clothes" , "Clothes drier" , "Where to dry what's washed" , "What launderers may use" .)
