Chic.
Fashionable; comme il faut; the mode. This is an archaic French word in vogue in the seventeenth century. It really is the Spanish chico, little, also a little boy, and chica, a little girl or darling. Similarly, wee in Scotch is a loving term of admiration and pride. (Chic is an abbreviation of the German geschickt, apt, clever.)
