They very massively, you'll need to try them on. Either in shop or someone like amazon where the returns are East and no questions asked.

There's so much variation. I suggest finding a couple that have size charts based on weight and then it's going to be trial and error from there.

I would recommend one size smaller than what you currently wear...

I was wearing a size 6x tshirt before surgery, and now I'm in 2x - of which some are feeling quite loose. I am in the gym between 5-8 times per week. I need some compression wear.

But at a 2x tshirt, I'm not sure what sizing to get. Any suggestions? Also, brand suggestions if you have any. Thank you!
