The dress is great!
Regarding the scrubby... you can take it a step further by making a pouf out of net or tulle that is similar in color to your hair, and you can make it any size you want. For more complex shapes, it's quite simple to make little pads and pillows of double layers of brown net and stuff them with ratted up yaki (synthetic)hair. Or if it doesn't gross you out, your own hair pulled out of the brush. The Victorians even had a vanity-top jar to save hair in called a "hair reciever".
