Sorry for the late reply .When I was in Dongdaemun I was qouted as the price of the Cheil VIP to be $50 a yard.
tailors in seoul korea? - Page 39
I would confirm with your tailor before buying. From my understanding tailors get a good profit margin on fabric, so they may not want to use something provided by the customer. Every tailor in Korea will have Samsung fabric though, frequently as a standard option.

I have started the process of commissioning a suit and blazer through Sartoria Vanni in Gangnam,
They seem to be a pretty good shop and their tumblr makes me think I will get some quality products. I don't know if it was through this thread or another, but I have seen someone post a few suit from them on the SF. Please let me know any experiences you all have had with them and any suggestions. Thanks and I will either post pictures and my experiences with them on this thread or I will start another.
