You need to get elastic from a doll supplier. I used regular "round" elastic when I fixed my daughter's Samantha. It is looser then it should be, but is holding for now. I've since purchased the proper elastic and will do the changes when the current elastic breaks again. The supplies I used are: round elastic needle nose pliers small brass eyelets You'll need to take the head off of the doll and unstuff her. Then cut the elastic in each leg. After this is one look "into" the leg, you'll see a cupshaped thing. Use the plier to take it out of the leg, carefully. Discard old elastic. insert new elastic into cupthing so that the rounded part faces you. Use a brass eyelet to secure elastic. (I used two.) Push down the brass eyelet and then tie a knot in the elastic to keep it in place. Replace the cupthing in the leg. Thread the elastic into the body and thru the second cupthing. Pull tight and put on another set of brass eyelets. Repeat on second leg, restuff and replace head. This should work. I hope I've explained it well. Part of it will become clear once you get inside the doll.
