I'm trying to save a few dollars by buying a suit on Ebay and getting a tailor to fix it for me.

I'm having the hardest time figuring out what coat size I am.

from Shoulder to shoulder I am 22 inches
If you measure me around the shoulders I'm 52 inches and under the arms I'm 42 inches.

I'm like 6 foot 3


What other measurements matter? What coat size would I be?


Thanks
