Simple Dresses for Clothing a Three-Year-Old Girl

Does she want to wear leggings? Jeans? Pants? Tights? A cotton dress works with any of those options. My 3yo loves to TWIRL, so the secret there is to only get dresses with drop-waist twirliness; that way she can run, jump, play, climb without it getting in her way. This is her latest everyday dress. I have Gap credit so it's free to me, but for the a few bucks more, you can get 2 similar dresses at Old Navy.
