you want good quality baju melayu then go to a good tailor and make 1. premade baju malayu with high prices are a scam.
the best baju melayu i have ever made cost me rm300 and it was done with a tailor in sibu. that uncle really knows how to sew soft delicate cloth. the neck area was reinforce with a thicker cloth and since my neck is short he adjusted it so that it really fits.
