OK I found it in one of my books that has an Italian AF uniform in Libya 1940. The uniform was overall white linen with a matching white padded helment. His boots were black and gloves appear to be leather. It notes that this is the summer unifrom and it would be olive-green during the winter.
I found alike with a photo from the USAF Museum

Hope this helps if not very late.
