Back when i visited it was rm1k to 10-11k bhat(with the proper money changer) id spend like 3-4k bhat for 3 shirts a suit and pants combo, but after a while of going to them prices got cheaper, like once it was 2 suits and 8 shirts for only 10k bhat (i paid him rm1k because didn't had time to find a money changer) I used to deal with a guy named amol or kamol something like that he's a big size guy his runner is called Shiva a very pleasant person to deal with.
