If you have ever had a costume presentation to make detailing a specific year, including the trends, music, events and other things that took place back then, you know how difficult it can sometimes be to find good, reliable information and (more importantly for us) pictures. There are a few places to check. Wikipedia is usually pretty reliable for background information. The People History has additional (though vague) information about prices of things, and a small blurb about fashion in the particular era. There is some info on Fashion Era, but not many pictures of actual garments. It is difficult to get accurate photos (and lots of them) in one place.
Enter Memorylane.com. Formerly known as classmates.com, Memorylane is a wonderful database of specific images on a year-by-year basis. It is a searchable database, full of images and videos specific to that particular year. No guesswork as to whether or not the poster of the photo had the year right. It’s lovely. Check it out! And good luck with your presentations!
