planning to get a casual blazer tailor made. anyone can help me recommend some good tailors around KL and can give me a rough price estimation?

this will be my first blazer and if it fits well i would like to proceed with making a suit as well.

my height is around 170cm with a slight athletic build. For work shirts im comfortable in those slim fit cut shirts and was wondering if i can apply the same style to blazers and what kind of 'specification' should i ask for?

Thanks in advance!
