I got this seventies pattern (sans cover) at the Lost and Found market the other week.
I wanted a fauxhalter (that is, looks like a halter but has a back) so I cut away some of the sleeve - I think I might scoop out a bit more. Sadly, the zip is pretty bad - I didn't have an invisible zip so I used a normal one - it's very rippley (and not in an Alien way) and I might have to do it again. I did a side zip instead of the back one as called for in the pattern. As you can see I am cleverly hiding it with my hand.
I also used the trusty skirt from New Look 6557 instead of the six-gore skirt in the pattern.
Fabric from Clear It in Brunswick street.
I think I need to make a few half slips - I have a fair few halter dresses which I can't wear full slips under, and also quite a stash of silk and lace trim. Plus, they will be quick to make...
Cue gratuitous picture of new and and existing kittehs in passout mode :
