I am trying to buy a MLB authentic baseball jersey online for a christmas present and I have no clue what size 40, 44, 52, 56 and 60 are or mean. The person I am trying to get it for is 5’7, 155-170 lbs and a 32-34” waist. I am getting it custom so I don’t want to get the wrong size and not be able to return it. Any idea what size I should order?
What size MLB authentic baseball jersey should I buy?
