I wear a 17 3/4 neck shirt with 32 waist...if you think you are swimming in your shirt you should see mine. I have called and asked for a tapered shirt...the response I got was that it already is.
So I spend about 15 $ bucks a shirt.

Tapered the sides...
Bring in the sleeves length and girth
Epelittes bar holder things, shortened
And then move up the pockets...

My lady I go to is a sewing ninja

After all that...I at least look like a professional.
