After a while you realize that people in general don't notice nor do they care, so you can relax and go about doing what you do with out worry. it takes a bit of getting used to, but once you get past it, it really is no big deal!
I have gone out in a bulky night weight prefold diaper and plastic pants under my shirts or jeans, and it wasn't 'obvious' but I could tell in the mirror :blush; and STILL nothing! i just went about my day and didn't really worry nor did I care...
So you get used to it....just one less thing to worry about and get in your way..
So ENJOY!
