It's just a shame she never replied to my emails when I sent them, but judging by her work she and her team do it very professionally and using good fabrics and lace. Tailoring is not an easy job, it requires a lot of work and professionalism for a garment to look really good. It's the details in the sewing and ironing after every step is very important so seams look flat and nice. My mother used to tell me that so many people don't realize that and it's why garments look sloppy, even many professionals can be sloppy.
It is so expensive in our countries because it's labour intensive even if you buy the fabric yourself on sale, it would be nice if there was a balance or being able to select your own fabrics. I faced this issue when I contacted all the other companies asking about silks, and they refused to tell me if they can get any because they kept quoting the low prices and saying it would cost so much more, but it was my request, and if they're tailoring for me I should be able to choose the fabric I want, I know the prices here in Canada and was willing to buy them at that rate but was pretty sure that in China they would be at least the same or a bit cheaper anyway. The message just never got across, and others refused to do it.
I just want to say to all the others out there to make sure they select a pattern and understanding the fabrics that they will use in China to make the dress. I would look closely at examples that they've done and see what fabrics are available and what would look the best according to their supplies and your taste. Over complicated garments are not always guaranteed to work out.
