Female repeatedly wearing short garment that's yellowy orange (7)
I believe the answer is:
saffron
This clue might be a double definition.
'female repeatedly wearing short garment' is the first definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'yellowy orange' is the second definition.
(saffron can mean a yellowy orange colour)
'that's' acts as a link.
(Other definitions for saffron that I've seen before include "Orange-yellow colour" , "Spice from crocuses" , "Golden yellow" , "Orange-yellow spice" , "additive found in rice" .)
