Pretty sure if you have the cash then anything can be ordered in any way you want! It always works out cheaper to buy a standard topper size rather than have a precise piece of wig made I think. This way it's also pretty simple to cut down and style, say, a freestyle piece to how you want it regarding style.
For a quiff in the U.K, I'm thinking it would equate to a brush forward with spiky front in terms of Hairpiece jargon. Regards
