Background: Boddy was bracing himself against gusts of wind down the street on a January morning.He strode down Newbury Street, wool cap pulled low, scarf tight around his ears and the rest of him buried deep in his down jacket

I notice that it's common to omit articles before nouns (wool cap, scarf) after the main sentence (He strode down Newbury Street). I'd like to know if this kind of omission is limited to literary works. Is it fine for causal writing or news reports?
