I needed a wig to wear to work on Halloween and this worked perfectly.  It has a "cap" base rather than just a flat inside, if that makes sense.  I normally have trouble keeping wigs in place, but this stayed on great all day without any adjustments.  It also wasn't itchy and hot like most costume wigs I've tried.  It's very full and the photo is true to what it actually looks like on which is refreshing.  The green and purple were very vibrant and it didn't need any "styling" other than to be fluffed up once it was on.  Great wig for a very reasonable price.
