In ancient Greek Mythology, Iris was the personification of the rainbow. This Iris is a versatile rainbow-trimmed dress. In cooler weather, wear it over a shirt, in warm weather, wear it on its own. The straps are attached in back via button holes, and so are adjustable in length, and can be worn three ways: crossed, straight, or tied halter-style. This allows the dress to grow with your girl. The pattern is sized for girls aged 2, 4, 6, and 8.
