I always thought that an untucked shirt looked kind of sloppy. Prefer a tucked in shirt. Always tucked in my shirt, always. Since I started carrying, I had to adjust that idea and become more flexible. Lately I've been enjoying carrying in my new DH Jit OWB holster. High and tight under a sweatshirt works well for me. I really don't like to leave t-shirts untucked, but I'm comfortable using a Remora in that situation. I use every holster I own, and dress accordingly. The Jit style works well under t-shirts also.
