This isn't my favorite Mia outfit. I'd give it an A-, though, because all of Mia's things are pretty cute.
The shirt is the best, and goes really well with plain jeans. It's a lot like the skating fan tshirts I see little girls wearing at the ice rink, so it's very realistic. I don't really care for the gray pants, but I never like sweatpants on dolls. I don't think the pants really look good with anything else.
The little extras are what really make this set. I use the mittens and the headband all the time with various other outfits, and the scarf is just adorable!
