Having time off, the lasses hang about looking decorative (7)
I believe the answer is:
tassels
'hang about looking decorative' is the definition.
I can't judge whether this defines the answer.
'having time off the lasses' is the wordplay.
I cannot really see how this works, but
'time' could be 't' (abbreviation) and 't' is present in the answer.
an anagram of 'lasses' is 'assels' which is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tassels that I've seen before include "Ornamental bunches of cords" , "Ornamental bunches of threads as on curtains" , "Tufts of decorative hanging threads" , "Decorations" , "Bunches of cords for decoration" .)
