Review (4/5): Will require some small adjustments, but pretty good overall (for the price)
Overall, pretty happy with the wig, but some general comments about it
The fit is great. I have a bigger head and thick hair, so I've run into a fair amount of wigs that are too small for me. It does have the adjustable straps in it, but I will say that it is just a ribbon with random lines sewn into it that you attach the hook into.
For how thick it is: generally speaking , it is a relatively full wig (as in, I can't see the wig cap by just moving my head). However, it is a bit thin at the top, so unless you are planning on either: a) cutting the bangs so you don't have to push them to the side of your face, or b) wearing a headband/hat to cover the top, anyone who is taller than you might see the wig cap.
And as for the color/style/shine: The style is what is pictured, but the color is more of a crimson than what is in the picture. It isn't as shiny as a party store wig, but it is a bit too shiny to be "natural." Both are pretty quick fixes, so it is really just a matter of if you want to put the time in it, or you just want a "grab and go" kind of wig. And like with any longer wig, it does shed a bit and tangle fairly easily.
I do want to mention that I was planning on cutting it to begin with (as I needed a shoulder-length wig for the cosplay I'm doing), and that I normally partially dye my wigs to help it look more "natural," so having to slightly dye the wig isn't a big deal to me. If you are fine with putting in a little effort into it, or just want a generic cheaper wig for a night out, then, yeah, the wig should work. But if you are expecting it to be exactly what is in the picture, then you might want to continue your search.
