Well, I got my pattern for the girls dress from Elizabeth Stewart Clark. I measured my daughter up and she fell between the size 3 and the size 4....
so I cut the bodice out at the size 4. Figuring that its better to have too big than too small.
According to the pattern chest circumfrence for size 3 was 30 and size 4 was 32.5. My daughter was 29.
Waist circumfrence for size 3 was 26 and size 4 was 28, and she measured 27 inches.
So chest wise a size 3 might have been fine, but on the waist it would have been snug.
I did cut out a bodice first out of scrap material and it looked like it would be fine. So I went and cut the bodice out of the good material on the 4, and now that its done, it looks like it is much to big for her. Especially in the waist.
At least she can grow into it!!
I actually had enough material to cut out a second bodice in the bateau neckline and short sleeves. I cut that out on a size 4 but have not sewn it together yet.
