My 3.5 year old is very very into clothes, accessories, shoes, you name it. For the most part if we're in a rush I lay an outfit out for her, but she always wants to choose the shoes (9 out of 10 times they're actually totally appropriate).
Today she added a tutu and pink cowboy boots to her t and leggings. I don't care at all, haha! As long as she's decent we go out
I love that she's creative and confident and really don't want to stifle that. I'm afraid it's so hard to get confidence back in the preteen years!
