I don't know if I can really pick... there are just so many options... but this might be one of my favorites that she's pulled out of her closet. And, yes, it IS another throwback - to last summer. My gosh, she looks like a little baby doll... and now she's a super sassy, back-talking 4 yr old. (I don't know about your kids, but mine don't hit the "terrible two's" until they're 3.5)
Can you believe how cute this is? Ok, so she didn't do this one ENTIRELY on her own, but almost. She came out wearing just the top and I told her she needed some leggings under since we were going to the park. She came down with jeggings. A perfect choice. I told her she needed a sweater just in case, since it was a tank top. She fussed a bit, but eventually came down with the yellow sweater in hand. Again, I approve. As for the perfectly perfect shoes, I strongly encouraged them, because they are, well, perfect. And she actually complied. What can I say, you just can't ignore deeply rooted sense of fashion.
I wish I could dress this cute for around $20 total.
