60s vintage summer dresses!

These are all from the same collection and I am not sure what size 17/18 in the 60s is.. but it’s not equivalent to today’s size 17/18. I added a couple measurement photos, the dresses are all the same style. Stretchy throughout and the belt is removable. Due to photo limitations I couldn’t upload all photos. Please message me if you want to see a particular dress with more photos or measurements!
