This image is so creative using the flower as a tutu. I like how the colors in this image are very warm and there is a little bit of orange in the flower. It helps the image how the flower is in focus but everything else is blurry.
The contrasting panels at the side of this dress draw the eyes into the waist creating a very flattering shape, not only this but the pretty spring colours, girly pleats and the delicate yet revealing lace add to the optical illusion this dress provokes.
