Depend the context: De luxe, luxurieux (food, hotel..), Chic (clothes)..
The English word chic was coined in 1856, being borrowed from the French word chic, having a 19th century meaning of "stylishness", but had, in the 16th century, the meaning of "subtlety". From there the path is somewhat muddled, having four "possibles". Please see the related link for more information, and note the word: chichi as well(!)
It means stylish, chic, trendy, etc.
Le plus chic is a French equivalent of the English word "poshest." The masculine singular phrase translates literally as "the most chic (decent, elegant, kind, nice, posh)" according to English contexts. The pronunciation will be "luh plyoo sheek" in French.
