UNCOMFORTABLE SHOULDER? forward shoulders

Does your suit coat feel as though its fighting you? Is it pushing back against your shoulder like all the weight of the coat is resting on the tip of the shoulder? And even though the shoulders look fine, upper front of the armhole feels too wide?
If the coats shoulder front is doing these things to you then you have forward pitched shoulders.
run your hands along your shoulder. You can feel a slight curve to the front, this is normal.
But you may have a pronounced curve. Thats what tailors call foreward pitched shoulders.
On m2m, and on custom/bespoke garments just call the tailors attention to this and all is well.

But on rtw suits, alterations are needed. Its called shifting the shoulders.
Flip up the coat collar. See the different cloth, its the under collar. And the cloth of the suit extends under there. All depends on how much cloth is under there. So here is how it goes.

The sleeves are removed, also the collar is removed except where it is attached to the lapels.
The shoulders are also opened up. all the linings are opened where needed.
The first diagram shows the neck hole exposed. the larger curve shows where the under collar was sewn.Now the front shoulder seam is shifted outward and sewn in that shifted position
Check the dotted lines. At the neck the cloth that was under hidden under the collar moves out.
And we have a new curved line at the gorge where the collar is reattached.
At the arm hole we now have excess cloth see that dotted line. This excess is cut off and we have a new armhole curve.
Now all that is left to do is to put all the pieces back together.

As long as the sleeves are detached, they can be re hung to suit your arms pitch.
At an extra cost naturally.

You might print out the diagram and show it to him.
that will insure that you are both understand each other.
you might also add another $$ to that.

if the tightness is all the way across the chest from the lapels
to the armhole. then its just too small a size for you.

this is one of the drawbacks of made to measure.
In m2m we are dealing with altering a finished garment.
In custom work the changes are made as the construction goes along.

Also when you are ordering from 3,000 miles away, and you are speaking
customer talk whereas the tailor is speaking tailor talk, plus the different
two language translations.
This is why i call ordering on the net a crap shoot.
You can win a beautiful suit or, you can receive a piece of junk.
m2m ordered from a local tailor increases the chances of success.
Thats providing he is a real tailor, and not just a sales man.

sorry but from your description i cant imagine what was done.
It just does not sound like tailoring.

yes the term refers to the shape of the customers shoulder, "forward pitched shoulders".
but among the tailors description of the job being done is, "shifting the shoulder.".
