Yunsil and Geewhiz... I don't think Yunsil takes one offs for quite some time now. All 10 or more. She is very expensive so is Geewhiz, although not as expensive as her. Then there is Add-Blue, just a host of very talented 1/6 tailoring. Mostly from Korea, exception is Geewhiz who is Filipino and I forgot about a Hong Kong guy...forgot the name he goes by, but very, very expensive. But sadly, their clothes are great, but it will run several hundreds to thousand(s) of dollars depending on the level of detail, but their level of detail is great! More than great. Superb. Their waiting list is a mile long, so don't think you can order something from them and expect it to arrive within a month...6 months to a year. There is the old adage, "You pay for what you get..."
Your best bet is what Stryker said.
