This dress is a super cute, top down smocked bodice dress with a wide flowing skirt. Knitting with fingering weight yarn and larger needles helps give the knitting fabric a light weight feel.
The pattern gives suggestions to make the chest a tiny bit smaller if needed for dolls who are tall and skinny.

There is something magical and delicate when you dress your dolls in a smocked bodice dress.

I like to use a size 4, 16 inch circular needle.

This pattern starts off knitting flat and then works in the round for a seamless top to bottom working.

I believe this pattern would be for a advanced beginner.
