Inside potential clothing store (5)
I believe the answer is:
depot
'store' is the definition.
(depot can mean a store or warehouse)
'inside potential clothing' is the wordplay.
'clothing' indicates the answer is hidden within the clue (the solution is covered or clothed by the clue).
'DEPOT' is hidden within 'inside potential'.
(Other definitions for depot that I've seen before include "Storehouse or terminus" , "Storehouse or warehouse" , "Storage base" , "Store for large quantities" , "Bus garage" .)
