Design a logo for children's swimwear range - may appeal to children's book illustrat

I would like a logo which depicts a new children's swimwear range called "Swim bunnies". The logo must be appealing to girls between the ages of 5 to 15 so cannot look too babyish. The logo will need to go onto the website as well as on the swimming costumes. The logo would need to identify that this is a swimwear garment, I have attached some inspiration however this bunny is already copyrighted so cannot be used. However the inspiration shows the simple shape and the character of the bunny in the drawings. The bunny may be identified as a swim bunny by the use of goggles of a swim ring or maybe flippers, whatever seems appropriate. It needs to be simple so it can be easily identified on the garment as well as on the website. And therefore is likely to be one colour so it can be transferred to any swimwear design.
