No length was cut, and extensions were only required for the cylindrical bun. The photos were taken under a roof, so the photo on the right shows the color best. It's a beautiful chocolate brown =).

Minimal length was cut. It's a thick wig that surprisingly didn't tangle that much, even through a dyeing process, provided it was stored properly. I've attached a photo of the original color. The color is a very light blonde, but it is still distinctly blonde, especially in a large volume of fiber like this wig, and should not be used as a substitution for white unless you really do want those blonde tones.

1-2 inches were trimmed all around the top area, and of course much more in the back.

A pack of extensions added for the larger spike, though the thickness and poofiness of the Punky was still very helpful for styling.

Pretty much looks black unless you put the wig next to a true black, and you might notice a difference.
