MoW is a great resource, however, you may find yourself having to switch out some of the items. A lot of his items are one size. His gear ships quick and the quality is great for a mass produced item. Makers on the cargo hold do limited runs and sometimes have backlogs resulting in a long wait. Alternatively, you can make your own items too. Something to consider: Fett is a long haul. Don't rush and do your research.
I've faced criticism on the following items:
Gloves are not accurate in color or stitching
The fight suit is two pieces and you will will have to dye it yourself.
Vest does not velcro down the back, rather it has two wings that wrap the body.
I believe I measured the girth belt at 29" from buckle to buckle.
Flight suit and vest may require tailoring, as it's a one size.
If you can get the boots in your size, do it now. He mentioned not doing future runs.
I have his jetpack, gauntlets, vest, neck seal, flight suit, boots, gloves, cape, and girth belt. I think they're great, however, in an official capacity, others seem to differ in that opinion. I've ended up replacing the vest, neck seal, flight suit, gloves, and cape for the official costume clubs, but they're all great for a casual quality Fett. It depends to what level you want to take the accuracy. Tailored soft parts are the way to go and his are one size.
There are a number of makers on the cargo hold, but in the interest of choosing your own items, you can shop around there too.
