I drafted the pattern from this 1930s Haslam Pattern of 'Step In's with a lace insert:
I found this lovely button which finished the 'Step In's perfectly. For the pattern look at the Filly bits website. The fabrics i used was some vintage 1940's peach silk and the inset is an old piece of lace.

I am really pleased with how they turned out and now Claire and I are moving onto the realms of slips.
