while editing this flash, my bumbling around as3 "created" this unexpected result. i'm not done with this yet, but i liked this accident enough that i thought it worth sharing. also, smaller file size than the original.
If you delete shape 23 (shoulder straps) shapes 63-66 (bra) and Shape 80 (bra also) shape 69 (current nip slip) you can make her topless and then add nipples to shape 80 and they look okay since they deform and warp with the breast shape. The problem is matching the colors and shading so they don't look out of place.
