Why are Asian women’s fancy clothes so expensive

Response:
The traditional Asian clothes are made using lots of expensive materials and a huge labour effort. On the average fancy clothes can take somewhere between 10 to 30 days and less fancy clothes takes somewhere between 5 to 10 days. 
The good tailors who understand client requirements are very hard to find and have limited capacity to fulfil large number of orders. As this is manual labour, automation can not help especially for customised sizes and designs.
The raw material used as well as expensive cloth increases the cost and requires lots of thought and aesthetic sense to make it look nice. You are paying for the quality as well as the unique custom design. 
Asian wedding clothes are normally the most expensive. Some high end brands use gold and silver threads to make the wedding day dress even more prestigious. An average wedding dress can cost from tens of thousands to hundreds of thousands of dollars.
