You know those victorian era judge wigs you see in classic Bugs Bunny shorts? Are there sims 2 hair cc that resemble those wigs?

@joandsarah77 has posted the same question years ago, but this hair was the closest they could find.

But surprisingly, I haven't found that hairstyle either for TS4 that could be converted.

So I think the best alternative would be finding a wavy/curly hairstyle that can be retextured with a curly texture (which you can request at GoS Wishing Tree or a Simblr that's open for hair recolor requests). Or a flat retexture from Maxis' Longsimple for males.
