This belt is pretty easy to make and looks good in my opinion. You can use any kind of belt buckle you want for it, I used D rings (Yes, I know, I don't have them fastened correctly, I always wear them this way because I'm cool like that.)

Step 1: Supplies

You will need the following:

Paracord (I used 550 cord)
A belt buckle of some type (Doesn't really matter, whatever you think would look best)
Patience
And some good belt weaving music, I chose the Old Crow Medicine Show.
Oh, and maybe some M&M's too. Those are always great when doing tedious things such as this.

Step 2: Measuring.

Measuring.....Well, In this photo I attempted to show one measuring the waist, then you would need to double that. This is false, I did not take in account for how tiny the weaves are, and thus, how much cordage is used.
But basically, You need alot of cordage. Alot.
Rather than the waist measurement and doubling, you might do good to triple this measurement instead, possibly quadruple to be safe.
after you have cut your mega long cord, Do this five more times, You should end up with 6 mega long strands, More if you want it thicker than this belt, less if you want it thinner.
Also, you can use any variation of colors you like.
Also also, If your strands are too short for whatever reason (like mine were) just cut some more, and burn that end onto the current end of the too short strand, You can weave where it was fused together into the back of the belt so it will not be seen.

Step 3: Getting It Set Up to Weave

*Cue fantastic weaving music (Once again, Old Crow Medicine Show was my personal choice, but you may want something else.)
Take your 6 mega long strands (or however many you ended up wanting to use) and clip them together at the end. This will be your top/Weave starting point 2.0.

Step 4: Get Your Weave On!

By now you should have eaten some M&M's and checked facebook a few times, maybe changed the song a time or two to play that one you really like.
It's now time to start the weaving process.
Do you recall making friendship bracelets when you were younger? Yes, it is that one basic weave, the one everyone always learns first, that we will be using today.

Here I have embedded a video of me weaving it, in case the photos confuse you (I learn better from videos than I do photos half the time.)

Also, I will attempt to explain in words how this is done.
Start with strand one, put it behind strand 2, then, bring 1 back around and put through the loop now made by strand 1 and 2, pull tight. Rinse, Lather, Repeat.
In other words, Take strand 1, and loop it around strand 3.
Then strand 4
Then strand 5
Then strand 6
Now 1 should be at the end, and 2 at the front. Start over, Start out strand 2, EXACTLY as you did strand one, work your way weaving down the line till you reach the end, then start at the start again with strand 3.
Keep doing this over and over and over again, until you have a fantastical belt.

Step 5: Just Keep Weaving, Weaving, Weaving.

Until your belt is big enough to go around you, plus a little room (Gotta add the belt buckle on there, remember?)

Step 6: Finishing Up

Add your belt buckle on. I have no photos provided for this, just because I am a lame-o and didn't take any. but yes, however you see fit and easiest, add on your buckle. Then, when finished, burn the ends so they do not fray. Before burning though, you might want to cut off some excess cord if there is any.
Also, if there are any M&M's left, Eat them, you need the extra chocolate boost after all that weaving!
