Starts over outfits keeping fashionable (7)
I believe the answer is:
origins
'starts' is the definition.
(I've seen this in another clue)
'over outfits keeping fashionable' is the wordplay.
I cannot really see how this works, but
'over' could be 'o' (cricket abbreviation) and 'o' is present in the answer.
'fashionable' could be 'in' (in can mean fashionable or trendy) and 'in' is found within the answer.
'outfits' could be 'rigs' (rigging is a kind of outfitting) and 'rigs' is located in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for origins that I've seen before include "So I grin (anag.)" , "Where things begin" , "Lines of descent" , "Parentage" , "Beginnings, ancestry" .)
