I bought this mainly for the denim miniskirt. My winter wardrobe centers around denim miniskirts in all colors, so of course my dolls had to have one.
I give the skirt an A, although I agree with Leila that it might be a bit mature for younger dolls. For a doll who is in 6th grade, I think it is fine. This skirt fits my 1995 #3 (the doll who I bought this for hasn't arrived yet) just fine, which is good news for those of us with PM dolls. I was pleased to see that you couldn't tell that the waistband was elastic.
The sweater and mittens are adorable and I love the colors. Another A. However, it is a little tight on my PM doll. I didn't have any trouble attachting the loops to the buttons.
I also got the legwarmers on just fine. A. My mom believes that you can't have the doll wear the legwarmers with the sweater, only with the hockey stuff, but I disagree and think they look very cute. Legwarmers are very trendy now, so I think they are a great addition to the wardrobe and can be worn with other skirt/tight outfits.
The hat gets an A-. I like the way it looks, but I am terrified of it pilling.
Now for the negative: I have two gripes with the outfit. One is that I have no use for the hockey stuff, since I don't have Mia and I don't plan on having any of my girls play hockey. I wish that they had been two separate sets, because now I have this stuff I'm trying to get rid of. I love the casual outfit, and think it includes great mix-and-match pieces, but I wish I had been able to buy it on its own.
I'm not going to grade the hockey stuff, because I haven't used it at all and I don't want it. The hockey puck seems like it would get lost very easily, though.
I also wish that the outift had come with tights, because I haven't located any of my tights yet and right now my doll's legs look, well, naked.
So I give the set a B overall, but an A for the casual outfit part of the set.
