The pattern is a top down dress, crocheted in rounds. No need for sewing at all.
The pattern comes in one size, fit for 4-6 years old girls.
I used 3.5mm hook, but you might need a 4 mm one because I crochet loosely.
Yarn needed: I used nearly 2 skeins of Alize Bahar Batik, and nearly one skein of Catania from Schachenmayr in off-white color for the middle of the dress.
The pattern is written, row by row.
