These clothing ads from 1928, featured on Jezebel, portray an ideal female form that is wildly different than the one we have today.  Note the straight lines (no hips or boobs) and very short hair cuts:

I also like how the first image reads “Summer 1928 Apparel.”   Seasonal fashion, it appears, is nothing new.
