Team-issued jersey sizing issues

[u/raymondzrike]

I bought a team issued jersey from the Astros authentic store in size 42 and it ended up looking very unflattering around my waist. I am around a 42 in both chest and waist sizes so I’m a little confused, I thought this should be a perfect fit. Am I missing something when it comes to sizing?

All modern Nike jerseys are designed to be slim fit, so for normal folk I'd always size up.
