I prefer the Original Trilogy style, which I'm wearing here:

There's another style, which seems to be more popular in the Rebel Legion, which is the Prequel Trilogy style. The OT style is easier to make, so that made my decision extra easy! The belt and boot colors DO need to match, so if you already have your boots, you'll need to coordinate with them.

If you're looking to source your belt and/or pouches, Civlized Galactic Gear does absolutely beautiful work and I've heard nothing but positive things about them. https://civilizedgalacticgear.com/

Boots

I decided to be strategic, and use my Imperial Officer boots for my Jedi, as that would allow me to pack one pair of boots for two costumes when traveling! If you think you'll want to put together an Imperial Officer, or a Han Solo, or one of the many other costumes that require black Equestrian boots, and you don't already have boots that you can use, I HIGHLY recommend that you spend a bit more and get multi-purpose boots! Your cheapest option, for men's sizes, would be PVC riding boots. They'll run you about $60 or $70. 

***February 2018 update***
I'm optimistic about these boots for men, available on Amazon. (***August 2018 update - I ordered a pair for my husband's Han Solo and I can now HIGHLY recommend them!***) They have no zipper, so they may be challenging for some to put on. The version with a zipper has the zipper in the back, which doesn't work with the CRL. Here's the women's version.  Perhaps, ask your local cobbler if a hidden zipper could be added to the inner calf. (Zippers don't work for level 3 Imperial Officer approval, however.) I've also heard of people having luck with http://www.sovietboots.com/ .  I had ordered a pair of officer boots from http://www.imperialboots.com/product/officer-boots/  for my husband, but that batch had some quality control issues. Their customer service was fantastic, however, so while that particular pair didn't meet expectations, I still recommend the company. If you need a zipper, they have them with a hidden zipper on the inside. I also want to add that I love my stormtrooper boots from them! Just need to finish my armor so I can actually wear them. . . .

I found my boots on ebay for $50! For ladies' sizes, I'd suggest searching around for a deal.

Here's the full CRL listing for Generic Jedi Boots:


For comparison, here's the boot section of the Imperial Officer CRL:

Officer Boots For 501st approval: Knee-high, black, lace-less, smooth non-textured, leather or leather-like material. Rubber is not acceptable. PVC or synthetic material is allowed as long as it gives the appearance of leather. There are no stretch panels, buckles, snap tabs, or decoration. Boots have conservative heels. If zippers are present, they are hidden on the inner part of the boot shaft. Not visible from the front, side or back. The top of the boots may be flat or Spanish Style, but not Cowboy or Super Hero (pointed at the front) style.

For level two certification (if applicable): Boots do not have a zipper.

For level three certification (if applicable): Boots are made of leather. Not vinyl or PVC. Exact replicas of English riding (dress) boots or Equestrian boots.

For approval, you need at least three of the four required extras: Inner tunic, Jedi Pouches, Food pellets (at least 4), or a Robe/Cloak. 

For this, you might want to consider the weather. A full inner tunic and an outer cloak will add to the heat, but will also keep you warmer in cold weather! The inner tunic can actually be a "dickie," so it doesn't need to add a lot of warmth. 

The food pellets are supposedly easy to make, but they're even easier to buy! I got a set of 8. Four went to my husband's Jedi, and four to mine!
