These are encylopedia-type books that overlook a time period, showing fashion, pop culture, political influences, important dates, etc. Interesting, browseable, and lots of fun. Here are few examples. Some are in the Reference section on Alden 2, in the E169-E174 area, and some are online.
Encyclopedia-type articles, photos, web links, chronologies cover popular culture. Look here for specific items of dress (ex: poodle skirt), designers (ex: de la Renta), eras, etc.
Careful when using the search box; it defaults to searching the entire Gale Virtual Reference Library -- several thousand reference books on all topics. I find browsing easier.
Articles about dress, textiles, some designers, fads, history, particular pieces of clothing (LBD, for ex.). There are 3 vols here; you have to use the drop down box to find vols 2 & 3. Here again, I find browsing easier.
