Tout managed with the French store (6)
I believe the answer is:
outlet
'store' is the definition.
(I've seen this before)
'tout managed with the french' is the wordplay.
'managed' indicates anagramming the letters.
'with' is an insertion indicator.
'the french' becomes 'le' ('the' in French).
'tout' with letters rearranged gives 'outt'.
'outt' going around 'le' is 'OUTLET'.
(Other definitions for outlet that I've seen before include "Opening permitting release" , "Opening, vent." , "Discharge pipe" , "Retail point" , "Vent, means of escape" .)
