The pattern is listed on Ravelry by designer Maxine Gonser. The link there sends you to Bev's Country Cottage where the actual pattern is listed. If you look at some of the projects completed with this pattern on Ravelry, some have made changes. I worked mine just like the pattern.
This is a quick and easy pattern. If you count out the number of stitches or shells listed at the end of each row, you'll be fine.
I used an H hook and Bernat Baby Sport yarn in pink. Here are two more pictures. The first shows the front and the second the back. The pattern calls for button closure which hasn't been done yet.
The pinafores came out less than a foot from bottom to top of sleeve. If you use a different yarn, you may get a different size. If you want to make it a longer dress, you might like to add more rows.
If it's cold where you are, you might like to put this on the baby over a long sleeve outfit.
Here is an actual baby wearing a peach pinafore I made a few years ago.
