Felted bag did not shrink 100%(may be superwash) any hope to

Has anyone a suggestion to help salvage this cute bag??
label says handwash to 104 degrees…it is baby fine 100% Anny Blatt yarn.
I washed as other purses I’ve made which felted fine…This one simply stretched bigger…

Sometimes yarn can strech as it felts (sounds like a contridiction, but is not). I felt stuff in a zipper pillowcase. and that has taken care of the problem for me.
