>>5734951Keep in mind this is all theoretical, it's just my thoughts and suspicions on the subject.
ThreeA started out in 1/6 scale. I think they leveraged the knowledge they gained about fabrics in that scale and used it to develop good clothes for 1/12 that matched the 1/6 as closely as possible. They definitely use some fabric types that I haven't seen many other companies use in 1/12. This is also a theory, but I think a lot of their clothes sit better because they're sort of put through the wringer. Whatever dyeing, soaking, washes and weathering processes they're put through seem to leave them feeling a little softer and thinner than what I'm used to seeing in this scale. A good example is Kuan Ti's facecloth, which actually feels pretty distressed, like a raggedy old t-shirt.
I also think ThreeA has simply put more time and effort in than most other slapdash attempts at clothing I've seen in 1/12 scale. It seems like an afterthought more than anything for many companies. That said, I don't own any Mezco One:Twelfth Collective figures yet, but they seem to be doing some pretty good looking cloth goods. And of course, the 1/12 doll-type clothes I own from companies like AZone are excellent quality--but they're also way fucking expensive, so I guess you get what you pay for there.
Pic related is also 1/12. Note the nice bunching of the boiler suit around the sleeve and calves--the fabric has enough give to do that, yet is stiff enough to hold the folds in place. That's some nice soft goods work there.
