Seashore Sundress pattern. I made it in a 3T for Sophie, she is tall enough for a size 4 or 5, but the rest of her measurements put her in a 3T. I have seen a few other versions of this dress that seemed longer, but I really like where the length hits on Sophie.
The fabric is by Sandi Henderson, Farmer's Market "Apple Dot"in pink. I have liked this fabric for a while, but haven't been able to track it down. I was so lucky to find a 2 yards that someone had returned to my local fabric shop! It's such happy fabric! Sophie loves her new "apple dress".
