Okay, I got the new skateboard outfit and took a photo of the top with this skirt. It's okay, but a bit of a stretch, especially with bright pink shoes! The bright colors overwhelm the muted tones in the skirt. Also, the white polo from the Tennis & Golf Set is too bright. You really need greys or pastels for this skirt.
ETA: I've more photos of this set in action.
First up is the top with Mia's meet skirt, for an outfit option:
Next is the skirt with two more tops. I think it's all right with Kit's sweater, but really, it needs something green or blue. An olive green or cream/ivory/offwhite/whatever would probably be best.
Finally, I've some photos of the jacket. Contrary to what Sara said, the design on the back is a combination of embroidery and printing.
I think the jacket fits quite well, and I didn't notice until I was taking it off Marelise, but the cuffs have velcro so that they fit over the hands better. Yay! :P
