I have no experience with Hockerty, but I have two general comments: First, if you want to invest in bespoke or custom clothing, please invest in a live tailor and not in mail-order clothes. There really is no substitute for a competent chap with a tape measure taking down your numbers and assessing your body shape and individual features. Second, clothes made in China are to be generally avoided, although there may be some exceptions. Most companies have their clothing products outsourced to that country to lower their costs as much as possible, and that means cheap, ill-paid labour, poor cloth and shoddy workmanship. You'll contribute to their profit, and receive badly-made clothes with inferior material in return.
The Chinese make many things very well (computers, for instance), but clothes are not currently in that category. That may change if these businesses are willing to pay more to good craftsmen and tailors.
