ever since i been going to bangkok to get suits made i stop getting them made in KL, its cheap, fast and quite reliable.

I usually get it done from a friends gf's father shop, he would send over his worker to come and measure me in my hotel and get it sent to me for fitting in the hotel too. Not too sure exactly where is his shop. I used to go to one quite a while back called Raja's tailors they were reliable too but since friend keep nagging me to use his gf's father i switched. this is the trip advisor link to the shop, I know how to go there by heart, just go onto BTS stop at Nana station exit towards Sukhumvit soi 11 alley, walk towards the alley and you'll see a shoe shop which sells quite decent leather shoes, literally to the left of it is the shop. IF you need your stuff done asap do inform them, one thing i loved is that they keep your record and can make your stuff for you and ship it down (i personally have mixed experience, ordered it like this 4 times 2 times needed suit urgently it came perfect twice ordered shirts and it was too tight, they fixed the error and sent a free shirt along )

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.

no worries, do try and head to the shop after you check in to give them as much time as possible to make your suit, do that even if you're going to a different tailor.

Shipping was in 3 day I would say i paid for FedEx due to urgency, but for in person 2-3 days is enough for whole suit to be done fitting included
