More thinking the shrug, with the shoulder Armour on the non saber arm. Perhaps some shin guards modeled in some crafting foam. And perhaps a saber belt with a Dropleg gunslingers rig for a blaster too? The costume pretty much says she's supposed to be a badass. A blaster has its uses. I'm thinking like sonethibg really heavy duty. Make it look like a sawed of e-11 rifle.
Yeah some kind of drop leg holster with a blaster might be a nice touch.
I agree with the glove idea too, although it doesn't have to be long gloves. You could do some short leather gloves, maybe even fingerless ones depending on the look you're going for.
