Really quick question on attire

1

so i have a blazer, a full sleeve button down shirt, and a full sleeve normal shirt (no buttons) that all match wonderfully. can i wear the blazer, the button down shirt fully unbuttoned, and then the normal t shirt underneath all of it? my whole family says they’ve never seen it done before but i couldve sworn i have seen it. this is all going to be on top of jeans by the way
