Since you've already chosen to have three, what I will add here will only echo what some others have said. You really only need the two straps on a traditional kilt. That being said, both my traditional kilts have three; however, that is mainly for the "look." So, do you need three? No. Have three only if that's what you want. I can't wait to see the new kilt when it's done, BTW.
