Review (3/5): Some flaws, but it's cheap, good color match and does pretty much what I needed.
I got the dark brown 4" short wavy style, as it looked the most like my own hair and I wanted something to cover up a bad haircut.
It didn't look very good on the mannequin in the description, and looks about as bad, or maybe a little worse, on me. As soon as I put it on I thought, "Oh, hello, Peter Brady." It definitely looks like a wig.
It also has lots of little ragged bits at the top where tufts of short hair stick up like cowlicks (I think they're poking up from the seams underneath), which looks odd and not like it's part of the wig's hairstyle.
If I needed this to cover my whole head, I would never choose it. However, the color is a good match to my hair, and I discovered that if I wear it like a sort of "beanie" further back on my head (secured in place with bobby pins) and leave my own hair in the front so you can see the part, then it looks pretty natural. And it was a good price.
