In a word: amazing. I love the mismatchiness. But I have to tell you, you would not believe how difficult it was for me to find outfits like this online. Now, I've used this scene as inspiration for myself before. I wear a sort of peasant skirt and a Mexican-esque top with a scarf around my hip and a scarf around my neck and a fedora. That's not quite what the outfit is. While there's no call to be exact because it is just an inspiration (for instance, the hat I've picked out isn't blue-gray, it's straw), I think it's important to get the pieces to be basically the same idea. The individual pieces all put together make the outfits in the scene so fantastic - the flowy floral skirts, the bright tops, the different colored scarves all over, the ballet shoes, and the hats combined with scarves. So, here's what I came up with:
the top - I realize I talked about how much I love the brightly colored tops but I was having trouble finding some that had the island look about them and that would looked good tucked in. Using the girl on the left-hand side of the second picture as my main inspiration, I decided that the outfit would be just as cute with a more neutral top. This one is from Modcloth.
the skirt - my goal in this piece was to find something that came just below the knees, that was made of flowy fabric, and, preferably, floral print. By the description, I think this one fits the bill. I found it at Anthropologie.
the shoes - aren't they adorable? I found them at Modcloth.
the scarves - I found them both at Modcloth: here and here. Honestly, I would choose just one and then dig through your closet to find a couple of handkerchiefs for your neck and head. I have obtained a few over the years but I don't know where you can buy fashionable handkerchiefs. Any suggestions?
finally, the hat - Again, this is not a blue-gray fedora but a straw one. While I do think there is much to be said in attention to detail, I really have to admit that the odds of someone getting where your outfit is from and then being offended that you are not exactly 100% accurate in your replication of it are pretty darn slim. If you're looking for a cute hat, Urban Outfitters always has an abundance of them, like this one.
