What you're looking for is a light brown long lacefront that you can part off to the side a little bit. I think you can get away with using a non-lacefront wig though.

This one is close to the color, but I'm not sure if it is a lacefront. This other one is a lot lighter, but it's a lacefront and also a good length. You can always trim your wigs to length, but it's harder to add length to a wig that's too short.

If you're willing to look outside of Amazon, I would look into this wig from Arda in Warm Light Brown. It looks a lot better than the Amazon wigs do and has a semi-side part along with being a perfect length already.
