Next question.
What body type are you?
Tall and thin?
Short and wide?
In between?
Muscular?
Not overly muscular, regular build?
Most off the rack suits will be centered around an average built person that is more or less straight up and down, not fat, not skinny, not muscular with pronounced size on arms legs and chest with skinny waist, etc. in other words just a straight block.
However, some companies tend to tailor their suits more towards a certain body type. For instance, I have a Pinnacle suit and it’s designed more for tall skinny people, whereas some other off that rack suits tend to be cut more for the average “American” body type of larger waist, not much definition in the calf to ankle area (just straight), and not much taper in the chest to waist measurement, average size arms. They also tend to run shorter so not good for tall skinny people.
We would need to know more about your body type to be able to recommend a brand since there is a lot of variance with how each one tailors their suits according to the market they’re targeting.
If you really want a perfect fit then you either have to be the exact body type these companies are fitting their suits to, or you go to JMJ and get a custom.
