"Hmmm, yes a bit.  The clothing shop was quite dark, and you were running around quite excitedly.  You are free to change, I would not want you to be uncomfortable." I smile.  "I quite like it."  I say I forgot something in my bag, and turn to rummage through it while you look at yourself in a mirror and look through the chest of new clothing again.  While you are distracted I drop the ring into my pocket.
