Be careful, $2,000 USD won't get you much more than one sport coat on the Row.
I suppose in your situation I would look at the dates of the next visit for some European tailors to Singapore.
Consider Steed, W W Chan (not European, but at that standard), and the Savile Row houses. I'd think your $2300 would be best spent in that fashion.
Having said that, nothing is as good for the mind as Travel, and if the jacket is a by-product then you've had a good trip.
