I confess that patterns like this one (in my opinion anyway) are what dressing little girls is all about! If it were me and I had a little girl to sew for again, oh wait...I'm fixing to have a little girl to sew for again, YIPPEE! I would make the dress in a chambray fabric or a light weight, light colored denim and make a few different pinafores to go over it. Then it could be changed up with half the sewing effort. :)
I don't know the pattern number or the copyright date on this one. What I do know is that it was designed by a woman named Helen Lee. Googling her name was the smartest thing I've done in awhile. Apparently she was a BIG children's clothes designer. She designed bunches of patterns for McCalls. AND get this in 1953 she won the Coty Award for her “significant influences in the development of good taste and charm in children’s fashion” now isn't that fun to read! If you take a gander at the Helen Lee link, you'll see that it is true...she had excellent taste in children's clothing and her patterns are a mixed delight of childrens fashions and artwork to look at. I didn't realize it until I Googled Helen Lee's name that I have at least 5 of her patterns in my vintage stash. In the future I will be looking for her name on the patterns I'm drooling over.
