I made this using McCall's pattern #3247. It's intended more as a summer tank top, not a smock. I added 2.5 inches onto the bottom edge and added the pocket.
The fabric is a JoAnn's brand cotton quilting fabric that was on sale and reminded me of the
old vintage sheets people have been posting lately. The pocket is sewn from a couple other cottons from JoAnn's also. It fits my new blank "list book" perfectly. There's a bit of bunching in the back if I don't get the ties just right and it's slightly tricky to put on and off even without unlacing the ties.
I wore this out one evening last week for burgers with friends. It didn't wear well when trying to hang onto and keep a squirmy almost 1 year old entertained during dinner while her dad and grandma quickly ate. The straps were all out of whack and the front was slipping down. I do like this though and will still wear it both as an apron and out of the house, but probably not as a tank top. I can't get away with that quite so well as all the cute, young hippie girls in their calico and corduroy open-backed patchwork ones can!
