If the price is right, I'm sure they'll make 'em any way you like 'em!
I believe Ascot Chang has a significant retail business now, and I guess this is what they thought would sell.
Edge stitching is very much a love it or hate it thing. The standard which I've seen on some French bespoke, and I'm sure elsewhere, is edge stitching, no placket and no pocket. But I have very definite preferences depending upon the shirt, and was blessed with a forbearing shirtmaker. Dress shirts: edge stitching on collar and cuffs, but with a placket with standard 3/16" stitching, no pocket. BD: as above but with standard 3/16" stitching on collar, cuffs and placket. Sport shirts: as with a BD, but adding a pocket on the left chest, and sometimes on both sides with flaps, if sufficiently rustic.
Nothing particularly right or wrong about any of that, it's just what looks best to me. To me a dress shirt just doesn't look finished without a placket, and a placket just doesn't look right with edge stitching.
