Hi. I am not sure if this is what you are looking for, but it's a McCalls #3183. Check out this link and tell me how it goes.

Thanks for checking but this is not the design I was looking for. Apparently they have used the number for a new design. It was a camp shirt with a skirt that had a slit on the side and pants with a mock draw string. The date on the envelope was 2001. Thanks again.

Try Ebay, amazing how many patterns that come up for auction.
