From what I have learned over the past few years: 1. MTM is needed for someone who have a normal figure but have a large drop because taking in 6 or more inches on the pants would be ruine the balance of the pants. 2. When buying OTR suit, stick with the brand of suits that fit you the best--even if the brand is not known as the best OTR suit maker. Here, when I say the best fit, it means that the jacket which requires least amount (or none) alterations on the shoulders, chest, and armhole. Every other seams can be opened for taking in or out with little risk of messing up the jacket. 3. To get really well fitting suit, you need a bit of luck. Not only you need a good suit to start with but well fitting suit also needs a good performance from your tailor, if it needs alteration. Your tailor is a human who can make mistakes. Hence, if the tailor happens to put his best performance on that day when he is working on your suit then the end result most likely be splended.
