Vintage fashion scrapbooks are a gold mine of trends and ideas for inspiration. They are also a great way to see how accessories were worn, hem lengths, hair and makeup. For getting a good idea of fashion from a specific time period, they are perfect.
This scrap book dates from Spring 1967, and shows junior fashions, in all their most glorious colors and prints. While the silhouettes may be simple, the surface design more than made up for the plain styles. If you are trying to date a dress, these are typical for this era.
These dresses are all from vintage Butterick home sewing patterns of that era. With so many cool vintage patterns for sale online, I think it wouldn't be too hard to look them up for yourself. I find these older patterns have excellent pattern instructions that are easy to work from.
There are current patterns from the "Big Four" that revive these looks too.
Here are back views with pattern numbers, so you can get a good idea about the styles, seam lines and silhouette. In general, junior style patterns were simple and fast to make, requiring a basic skill level with few fitting challenges. Even now using these patterns are a good way to teach yourself to sew fashion.
