You quickly discover that your shoes, socks and pants won't fit in the skin tight costume legs. So you strip do to your civvies, and find that the suit gives you a terrible wedgie. You still want to try it on, so you go commando. The costume sculpts to your body like a second skin.
You pull the head on and stand in front of the mirror. It's so lifelike. You raise an eyebrow, and the lioness mask does too. You swoosh your tail, and amazed how natural the costume feels on you.
