I am thinking to get in touch with what you have mentioned. I am talking about fitting dress shirt.
I am thinking that what if any one can design his own dress shirt and get stitched with his own fitting size???
I have experienced this, what I am talking about! at stitchedforme.com where I can design my dress shirt also I can select the fabric and get it stitched fior me.
What I am thinking right now is that you can get your desired shirt with your fitting and get it stitched according to your design.
