I love love LOVE this outfit.
The girly ruffles on the trench provide an interesting contrast to the preppiness of the striped tee and tulip skirt. It doesn't look choppy, though, because the colors--khaki, shades of blue, and white--share the same nautical vibe. Olivia pulls it all together with an amazing oversized bib necklace.
PS - To all you Runway girls who don't think you can wear a navy dress or skirt with black heels...yes, you can. Check it.
