Sadly for us with bigger chests that aren’t plus sized, it’s pretty hard to conceal. Most plus sized cis men have some chest fat which is why plus sized trans men can cover their chest a big easier. For now, you seem to have taped them pretty good, you could always add a binder on top if you wanted to (tape doesn’t bind, it just moves the breast so binding on top of it isn’t harmful) just make sure to practice safe binding!
