Short skirt that’s taken in very loud yellow (7)
I believe the answer is:
saffron
'yellow' is the definition.
(I've seen this before)
'short skirt that's taken in very loud' is the wordplay.
'short' says to take the initial letters.
'that's taken in' indicates putting letters inside.
'very' becomes 'aron' (I can't justify this - if you can you should believe this answer much more).
'loud' becomes 'ff' (a musical term).
The initial letter of 'skirt' is 's'.
'aron' going around 'ff' is 'affron'.
's'+'affron'='SAFFRON'
(Other definitions for saffron that I've seen before include "Orange-yellow spice" , "Golden yellow" , "Orange flower part used in flavouring food" , "Flavouring derived from a species of crocus" , "Yellow spice" .)
