How do you disguise an outie?

I know what you mean. I also have a really big outtie, bigger than anyone I've seen, and it also shows through shirts. Mine looks like a big snail sitting on my tummy and also gets a lot of comments. I used to be really shy about showing it, but a couple years ago I had a boyfriend who liked to play with it and I really enjoyed the feeling of it. Even after we broke up, I gained a lot more pride in having such a unique belly on and I often show it off when I go out or to the gym. So my best advice is to let your belly on show so you'll be more confident about it, even though you might get some nasty comments, since someone someday will fall in love with its uniqueness ;)
