TL;DR: My gals may be strong, but their clothes have no pockets. Does it really have to be that way?
The early piratey uniforms had a 1x3 slot in the back: a bit limiting perhaps, but still quite useful. Since some time, however, all my best armors are flying armors and those (at least all I've seen so far) have a jetpack instead. These days, if I want to bring a sword (or similar) for storming the bridge, I have to hold it in my hand during the preceding gunfight.
I just noticed that my gnome actually has a sizeable backpack (TAC7-S). Of course, being a weak gnome, she can't really make use of it. It feels a little paradoxical: the strongest gals have the least baggage space, and anti-gravity equipment makes it worse.
