Goodness, this set is as cute in person as it is in the catalogue. I'll add pictures later, but the camera's charging now.
Green shirt: very cute. I love the green color. My only complaint is that the seams attaching the sleeves to the body make it look a little bit like it's inside out. It seems sturdy, and like it will be pretty versatile for me.
Jumper: Cute cute cute. It does sit a little lower than her chest in person than it does in my head. There's lighter purple vertical stripes on it that I didn't notice in the catalogue. The bow on the lacing is tacked down so you can't untie it, but the loops are real, so you could adjust it so it's tight in the chest and loose in the waist if that tickles your funny bones.
Boots: They're using a plasticy velcro that I haven't seen before. I like it - it seems less likely to accidentally catch on delicate things like tights. I worried I'd have trouble getting Willow to stand in them, but it wasn't hard. (Josefina, who's floppier, might have some issues.) Other than that, these aren't that exciting. They're boots, what do you want?
Hair clips: I'm not crazy about clips that hold about three strands of hair, either for dolls or for myself. They're cute, though, for what they are - they have both purples and greens in them so they look great with the outfit.
Overall: A. Worth $26? Hmmm. I wish AG's prices hadn't gone up, but they have. I think this is one of the nicer outfits that you'll get for that money and I like all the parts to it. Would buy again.
ETA: The pics I promised to add eons ago. ~_~
My best attempt to capture the color of the hair clips:
I really like both pieces as mix and match. The jumper goes well with a couple other blouses I have:
