The film stars always wear the most fashionable apparel
dumi: most fashionable outfits. Could you please tell why outfit is used, but apparel isn't?
Well... as you mean, apparel refers to cloths. But in your sentence you mean about fashionable cloths and "outfits" ( definition -A set of clothing, often with accessories) is the best word to give that mood to the reader. There are so many synonyms for cloths such as dress, attire, outfit, apparel etc. But these words are used to give different moods.
