Update:
I guess could talk a bit about the design. I did some research on space suits, and sort of combined two different designs into one. The puffy sleeves and I guess the head and chest area too come from modern space suits, which as far as I understand, are filled with air to pressurize them. The cap she wears is going to be basically exactly what astronauts wear today, called a snoopy cap, it's a cap with a headset attached.
The bodysuit part comes from a type of space suit that's still in development, that instead of using gas, applies pressure directly on the skin, making it a skin-tight bodysuit. I've read a little bit about it, apparently prototypes already exist, but they are a bit inconvenient still because they take hours to put on.
My design is kind of a synthesis of the two. I imagine the cloth underneath would consist of three different parts, the skin tight sleeves, the bottom half, and the puffy jacket. Once put on, these three would be connected somehow to make the whole thing airtight, and then the armor parts would be worn over that.
The helmet is detachable, not sure yet if I'll model it at all, but if I will, she'll be holding it and not wearing it, because I don't want it blocking the face. Still thinking about what kind of gun to give her, but I really like the idea of a plasma sniper rifle.
