WhooHoo, I found some new hats for Toni and at a very reasonable price. They are actually miniature hats for photo ops for babies or cute dogs, but why not for dolls as well.
The crown of the hats are not large enough to fit down over her head, so they sort of perch on top. This is shown on my Toni p-90. Each hat is glued to a hair clip so it easily clips to her hair at whatever angle you think most attractive.
The colors are soft pink, deep rose pink, black, dark blue, scarlet, and deep purple. That should suit a lot of outfits in her wardrobe with a matching color or as a contrasting accent color.
Each hat has some netting, feathers, and a flower. I experimented with turning up the brim on one hat, just on one side. It changed the look a little and I could glue it in place to keep it like that.
