When we were in Vietnam last year, I had several shirts and a couple of pairs of shorts and trousers made. Narelle had 3 dresses and a pair of trousers made too.
I have no idea how good their skillz are as far as suits are concerned, but the care, styling, fit, fabric, and stitching on our stuff was as good as I have ever seen, regardless of cost.
Overall, we paid very little.
I plan to have a suit made next time we are there. I shall bring it into you Ritchie and let you critique their work.
