Our little club has bought many of these keiko-gi's. They suit the girls as well as the boys, and yes they have 3/4 length sleeves.
From our experience, the size you choose will seem a little too large when you first try it. They do shrink with washing and drying of course, but if you're quite slim it might be worth trying a size smaller. The intermediate weight is recommended for durability and holding its shape. It's not Tozando, Seido or Iwata quality, but it's a good working keiko-gi.
Certainly you can email NineCircles to get their recommendation for your proportions. They're pretty responsive.
