Dressing with Etiquette (Part IV): Evening Gowns

Now that we've covered the basics, we'll move on to specific costumes for specific periods of day (in 1918).  Our first focus is on evening dress:

Full evening dress demands one's most elaborate gown, made of silk, satin, velvet, lace, or crepe-de-chine, as costly as one's purse permits, with decollete effects, gained by either actual cut or the use of lace and chiffon.  One should wear delicate shoes, white or light-colored gloves, and appropriate jewels, of which it is not good taste to have too lavish a display.
