Uncomfortable one unlacing bustles (11)
I believe the answer is:
uncongenial
'uncomfortable one unlacing bustles' is the definition.
I can't judge whether this definition defines the answer.
'uncomfortable one unlacing' is the wordplay.
'uncomfortable' indicates anagramming the letters.
'one'+'unlacing'='oneunlacing'
