Deep in a forest, carrying protective clothing (8)
I believe the answer is:
pinafore
'protective clothing' is the definition.
(I know that pinafore is a type of protective clothing)
'deep in a forest carrying' is the wordplay.
'carrying' says the answer is hidden in the clue.
'PINAFORE' can be found hidden inside 'deep in a forest'.
(Other definitions for pinafore that I've seen before include "'HMS - - ' G & S" , "Musical craft" , "Gilbert & Sullivan operetta 'HMS ........'" , "Apron-like garment" , "It protects female worker" .)
