might be something else to consider, as this is often the meaning of "confectionné", especially with reference to knitwear and hosiery, e.g.: Il est confectionné « fully fashioned » en une pièce – les manches y compris. http://www.proidee.fr/fashion-classics/femme/pulls-twin-sets...
It occurs regularly in relation to polo shirts, e.g: The fully fashioned shirt collar and the block stripes make this garment a deluxe polo shirt. http://www.proidee.co.uk/fashion-classics/men/t-shirts-polos...
or: In general his golf shirts have three-piece collars—that is, they are fully fashioned (knitted seamlessly with the rest of the garment to conform to body lines) and stand up a bit on the neckline. http://sportsillustrated.cnn.com/vault/article/magazine/MAG1...
This Canadian document gives the following definitions:
A "tailored collar" consists of one or more pieces of material which are cut and sewn or cut and fused and designed with two pointed or rounded ends.
A full-fashioned collar consists of one piece knitted to shape collar.

I believe it does in essence mean that the collar is tailored, rather than just being a spare flap of fabric simply turned down... However, I don't know if that is usually described in EN as 'tailored' or not.

Just one parting thought — seems unlikely, but I wonder if it in fact refers to 'neckline' rather than actual 'collar'? I'd have thought not, as it is talking about a shirt, which one would expect to have a collar, after all!
