Why does my character get stuck in T-pose?

I have this weird problem with my character controller. I allow changes to things like gender and costume by destroying the current character object and instantiating the right one. That causes the character to get stuck in a t-pose, however. I tried doing animator.rebind, but that didn't seem to work. For some reason, switching the avatar fixes the issue, but that would be a janky solution. Here's my code for reference.

    animator.avatar = genderData.gender.Equals(Gender.Male) ? maleAvatar : femaleAvatar;
    if (currentOutfitObject)
    {
       Destroy(currentOutfitObject);
    }
    currentOutfitObject = Instantiate(genderData.currentOutfit.currentStyle.outfit, gameObject.transform);
    animator.Rebind();
