Delicate embroidery originally attached to leather pants (8)
I believe the answer is:
Here is my best explanation:
'delicate' is the definition.
('ethereal' can be similar in meaning to 'delicate')
'embroidery originally attached to leather pants' is the subsidiary indication.
'originally' suggests taking the first letters.
'attached to' says to put letters next to each other.
'pants' indicates an anagram (UK informal term for \'nonsense\' or \'rubbish\').
The first letter of 'embroidery' is 'e'.
'leather' is an anagram of 'thereal'.
(Other definitions for ethereal that I've seen before include "'Extremely delicate, almost not of this world (8)'", "Airy or supernatural", "Light and delicate in appearance, heavenly", "Having great lightness and delicacy", "Having an unreal lightness or delicateness", "Impalpable", "Heavenly - fairy-like", "Insubstantial or heavenly", "Very delicate - tale here (anag)" and "'Fairy-like, delicate (8)'".)
