I'm working on a Tsuna cosplay currently
(I just need to make the gloves and get the ring... I also need pants. LOL) but I discovered that most people just don't sell wigs with enough volume and hair for Tsuna. So I just found a long wig that had the same colour as Tsuna's hair colour, and then I cut it (making sure to keep sections together after cut.). I then crocheted the leftover hair through the cap to add more volume and height (I secured it with Gorilla Glue after). Now it's just perfect!!!
