Going off of his newest design in the manga (beware spoilers), I'm making the jackets here:

It's a lined jacket being made completely from scratch, because store bought jackets don't really allow for the modification that this one needs. The pants are a pair of black pants I already owned, with long white strips handsewn onto the sides. Yeah, that was a major pain.

The knives were made for me by a friend, who also cosplayed my TYL Squalo. I couldn't be happier with them :3
