First off, sorry I don't have a Mia to put this outfit on! I technically don't have the entire outfit since I don't have the purple hair bands. But they're just hair bands, so no problem.
So here's all the clothing. I personally never saw this outfit as incomplete due to the hem. I recall having some outfits that rolled up similar to these PJ's, and they kind of give an airy feel to the outfit like Leila said. Also, wouldn't you want light-weight fabric for PJ's? Granted Mia's stories take place during cold weather when she can skate so some warmer fabric would of been a smarter choice, but light-weight fabric isn't too crazy an idea.
The PJ's are cute and easy to put on. What else can I say?
At first I had some difficulty trying to figure which part of the shoe is the heel, but it's not a big deal nor is it hard to figure it out.
The pattern on the pajama's pants.
And a matching one on the shirt.
This is the little lining on the top of the pajama shirt. 'Tis cute.
There's a lot of space between the front and back shirt, though it's connected at the sides so it's not difficult to put on.
