5 Layer Unbirthing Suit

This is a 5 layer unbirthing suit as discussed.  She will have eyes/ears/nose/mouth/hair, and arms/hands/fingers, on an approximate 30" torso that is stuffed.  Coming off of her torso will be a 9-10 foot tail.  The tail will be dark purple sherpa on the top with magenta circles, and a white fleece scale underside. There will be a zipper on the underside of the tail where it meets the torso.  This zipper will have a double headed zipper so it can be opened from either side.  There will be white "lips" on either side of this zipper, with hidden zippers for additional stuffing.

There will be 3 layers of padding in the tail, and an outter zipper to allow for additional stuffing to the tail.  Inside the tail will be a pink spandex liner.

*Should the outter layer be slightly smaller than your plush snake?  And how constricting would you like the inner liner to feel?  Just "touching" your arms when they are at your sides?  Or snugger?  Or??
