I bought a Kuwahara one off ebay yonks ago.
With pads, body armour, race gear, change of clothes etc, etc they just wont all fit in!!
So yeah, they're basically a man bag!!
You'd be able to fit in your make-up, a couple of glittery shirts and few pairs of novelty animal thongs and thats it!!
Mine is stored securely in the attic so it doesn't turn me queer!!
