Hello, all!
Haven't been on the RPF in a while, but I'm back! Yay.
Anyway, I'm putting together a Gary King costume, and am almost done. Much of the info I gathered is mirrored in this thread.
The Glasses: Beery's link from Amazon looks closest to the screen-used ones, and are more accurate than the pair I bought from Wal-Mart, including the curved bridge piece, so I'll be upgrading tomorrow!
The Jewelry: All good research being done here. The Eye of Horus on the leather choker cord is most likely based on Vision Thing by The Sisters of Mercy, being the reason Gary wears it. Also with the Ankh and Kneeling Isis. Egyptian symbols and mysticism is very prevalent in the Goth genre. Great work on identifying the Isis pendant!! I assume the dogtag chain was used to give the Eye of Horus some breathing room.
The Rings: I've been trying to get out to some flea markets, as they're a great source of costume jewelry. There's no way I'm spending over $100 per ring just to have the originals! I'm curious though whether the company that makes the skull rings worn by Gary had made those same designs back in 1990.
Thanks again for all the terrific research!
The Shirts:
For the SOM t-shirt, I bought a short sleeve version, and found a long sleeve black t-shirt and will cut off the arms to make the cuff part that covers his hands. Not the best solution, but I rushed to buy the t-shirt the minute I realised what it was - when I first saw images from the movie back in early July! The black snap shirt is slightly different than the Wrangler link Beery supplies. There are shoulder epaulettes on the one Gary wears. But these will be covered unless you don't want to wear the heavy coat!
The Coat:
I just found a good black trench coat yesterday at the local Goodwill for $10. Slight differences to the Gary King coat: Not the same style of epaulettes, but I'm removing them anyway, and I don't feel like being so super detailed that I'd sew on a tab on the right shoulder!

Also the cuff adjustment things need to be removed, as do the buttons and replaced with domed silver ones. I've a little work to do, but it looks fantastic and fits perfectly. Plus it's nicely used. I'm so happy!!
The Belt:
I decided to just make one. Picked up my supplies from Tandy Leather and Springfield Leather Company. I have to make the slip of leather the conchos will connect to, as well as dye the belt blank black. Got a Southwestern style buckle at Tandy, and the conchos from Etsy. From what I can see in the pics, there are 8 total conchos, 4 to each side of the buckle. There might be some around back, but we never see that. I'll post pics when I'm done!
The Jeans:
From what I can see in the poster, they look to be very expensive slim fit jeans. The wash is not just flat black, and there's some whiskering throughout. But I'll just stick with some cheap black jeans.
The DMs:
Yes, Gary wears circa 1980s Doctor Martens. There's really no other brand - they're synonymous with Brit counterculture. After much research, I agree that they are classic pre-2003 (Made in England) 1460 Doc Martens, with 8 eyelets. There's a very good shot of them here:
?The World?s End? First Look: Simon Pegg, Nick Frost and Edgar Wright Reunite On Set Gary riding Andy piggy back. They are not the earliest version of the 1460, which was free of the small lip at the very top. You can see in the photo that Gary's boots do have the lip. I happened to find some of the same Docs from a seller on EBAY:

They're nicely worn, still in great condition, and cost a total of $30.00! I just had to buy new laces.
So a quick primer if you want Gary's boots: Look for Doctor Martens 1460 8 eye boots, that have the "Made in England" stamp on the sole (by the heel), the yellow stitching along the welt, the "DMS" sole pattern, the lip along the top rim of the upper, and does NOT have the Dr. Martens logo hard stamped into the side of the boot's upper - this is a key way to spot a post 2003 boot made in China.
Looking forward to completing the costume so I can show it off!!
