Sunshade worn by Italian tourist (7)
I believe the answer is:
visitor
'tourist' is the definition.
(eg a visitor to another country)
'sunshade worn by italian' is the wordplay.
'sunshade' becomes 'visor' (a visor shades one's face).
'worn by' is an insertion indicator (I've seen this in other clues).
'italian' becomes 'it' (abbreviation for Italian).
'visor' enclosing 'it' is 'VISITOR'.
(Other definitions for visitor that I've seen before include "She calls" , "One coming to call" , "Caller, guest" , "who might stay?" , "Someone calling (again at 23?)" .)
