Rainbow Line Miku Glory 3usi9

I`m not certain if you`re going to receive this message, or if you check this account any more, but I have been meaning to create this dress as a cosplay project, and was wondering if you used an already-made pattern, or if you created one yourself. Regardless of which of these is true, would you have a way of leaving a link to the pattern? If not, thank you for your consideration, and I absolutely love the dress.
