The reason for the strap is the Fall Holiday outfit version of her character had it. And Rita liked that outfit slightly more than normal. Plus it seemed that the shop had the right weapon with all the right looking accessories as a set on sale. It's an accurate set, enough to have the shitty little failed fall leaf drawing on the gun, as well as elsewhere.<br/><br/>It fits rather snugly once Lapine helps get it on Rita; a fact that Lapine gets to further enjoy as she helps Lapine gather things. The AR boing sound with each step has to be intentional.
