You take another look at yourself in the mirror, and smile. You had the leotard, boots, gloves, and a cape, now you just needed one more thing to make your new look complete. With that, you spotted the knight's helmet, and sword as you knew exactly what to do with them once you grabbed them both.
You of course had no interest in changing the sword, but you placed the knight's helmet on your head, and watched the metal shrink around you, and change, until it became a silver tiara to match your new role as queen. "Finally, my outfit is complete," You say. "As for this sword, I'll keep it as a reminder to the heroes who I changed first. Without their leader, they will be useless, and I know they will come. Tigra, Arctia, get me the smartest scientists this world has. I must conquer it, for it's what my mother wanted."
