Flower Girl

In my opinion, one of the hardest things to pin down is what I want my 3 flower girls to wear. Every flower girl dress I see is either way too over the top, or looks like my 3-9 year olds are trying to be 25. Where did the happy medium go? Aren't little girls suppose to look "cutesy?" That said, little girls also grow like weeds, so how soon can you really pick a dress for them to wear, when the likelihood is that in within a few weeks they'll be growing again?

So far, the dresses below are the only real option that I have entertained... thoughts?
