Ah yes - Mr Southpaw mentioned the trench in his reply to you. If you look at the first page of the trench sale thread though, you'll see that his tailor has also patterned a short coat which you may be able to order and it should also exceed the quality/accuracy of the eBay offerings if the trench is any indication!
I couldn't find the trench sales topic, I word search-functioned project runs and junkyard. Got a link?
His jacket is nice, but I'm looking for the short jacket he wears for most of the film, which we first see him wearing on Xandar.
Right. Ebay models of the short jacket are slowly evolving the details.
When I was looking for my jacket in Sept/Oct the most accurate one out was cosplaysky. It had the correct bicep bands and the button flap on the right side of the jacket ran all the way up to the collar. Too red though, way too red. And it was and still is $159 for synthetic leather which is too high priced.
So I went on ebay and bought the 'Guardians of the Galaxy STARLORD Chris Pratt Red SLIM FIT GENUINE Leather Jacket' from seller 'ultimatecollectionz1982'.
Out of all the ebay jackets, again at the time, it had the accurate bicep-strap setup instead of the strap and brass buckle that the other jackets used.
I had it custom sized. They did an excellent job of making it fit right. I asked them to leave out the puncture holes on the jacket, they did...but also accidentally left out the diagonal strips on the chest area. They offered me $50 back for that. Throughout the whole process were responsive and answered questions quickly when I had them.
The problem is that they didn't sew the seam that runs lengthwise down the arm tightly enough. At the wrist the seam splits apart about 1mm, enough to let light through. That was actually a recent discovery made by a friend when he was considering his own purchase. I am currently waiting for them to respond to that.
Now recently, I was looking at trench coats and discovered some new ebay Star-Lord stuff. Specifically a very inaccurate vest listed under 'Guardians of the Galaxy Chris Pratt Red Leather/Jacket Gift for Christmas', and this new short jacket listed under 'Guardians of the Galaxy Star Lord Peter Quill Leather Jacket Cosplay Costume New' from seller 'uniteddoremo'.
This new model is the short jacket I have my eye on now. It seems to be a clone of the cosplaysky model. It has the bicep straps, it has the correct collar setup, it has most of the correct "brass buttons", and it even looks to be made with a little tuck in the waist.
The problems (which are small and they should be willing to correct if you pay for custom) are the two-prong "circuit" design on the front left chest/shoulder area. Instead of a piece tucked under the leather and sewed in, they just made it two flaps on the surface of the jacket, it's ugly and I'd probably ask them to do that different.
The small strap under this "circuit" area has the wrong metal piece woven through it. It should be like the jacket I bought, a rectangle with a straight bar through it. I don't know if I care enough to have them correct that, the piece they used is kind of neat.
They forgot the brass "button tops" on the sleeve flap corner under the bicep strap, near the elbow. So I would ask them to include those.
The real jacket has slanted cuffs. Check out the first page pictures. No ebay jacket does this, and it's something else they should be able to do easily if you get custom size.
Also, I'm not 100% on the color, it's kind of like dried blood but it could be lighting or something. I'd probably ask them to confirm that it's not brown.
Now the potentially awesome part. They have this jacket listed as real leather for $69.99, there is no pulldown to choose synthetic nor any mention of synthetic in the item description. Also, they do customization but have no fee listed. I think someone ordering this could end up with a china-made custom leather Star-Lord coat for $69.99+tax/shipping.
Basically, if I can get a refund on my first jacket for the defective sleeves I will probably go with this model myself. The collar detail especially is something that can't just be easily remedied and I'd rather just buy a jacket where it's done correctly in the first place. But again, I have not actually ordered this, so I cannot give details as to the in-person quality.
I hope this helps at all. I am hardly an expert on this, but I am willing to share my observations on the matter. If you want me to clarify anything I said in my ramblings, feel free to ask.
One last thing, this new short jacket I talked about actually comes with a valve on the right arm. But it's very ugly and incorrect. I don't know if I'd want it included or not.
