Boba wears 2 belts. One is a rope belt, or more to the point an girth belt for a horse. These are very easy to find, but it's really hard to find a good one. You need to dye it, so a synthetic one will not work out well for you. Wool, mohair, any natural fiber should be fine.

For RotJ I needed a dark red. I used Rit dyes, since they were easy to get. Scarlet with a bit of dark brown.

You need to add straps to the belt, since it doesn't come with any. I used a couple of strips of leather that I had available. Many people use nylon webbing.

The second belt is the ammo belt. This is leather or vinyl, medium brown, with 8 pockets. There are a variety of methods to make it. Some people form vinyl over balsa wood blocks, some people come up with ways to make the pouches usable.

My belt was custom made by NyghtCraft

The stitching on the pouches and belt are one of the things that makes the ammo belt distinctive, along with the grommets in the back. The ESB belt is quite a bit different, though at first glance they look similar.

I made the belt pouches using the same pattern that I worked up for the Scout Trooper pouches I had made right before this project started
