Concealed Carry Clothes - Compression vs Standard T-Shirt/ Muscle Shirt

I am going to be starting the process of getting my Texas LTC and plan on carrying AIWB 99% of the time (1% OWB when my partner and I are doing something like walking a trail or doing anything in nature). I have a little bit of a gut , so I’m worried that will make appendix carry difficult.I’ve talked with some friends who appendix carry and they are kinda split down the middle between wearing a simple cotton t-shirt or muscle shirt or wearing a polyester/spandex compression t-shirt or muscle shirt. I wanted to get the opinion of multiple people from all different genders, sizes, etc.Edit: I forgot to add this to the original post. I am talking about a tucked in undershirt to give an extra layer between the holster and the skin via /r/CCW https://ift.tt/3yhYwGG
