Ash - get your underthings before you alter your dress. You should anyway, because then they'll alter it to EXACTLY what you need it to be. Including making adjustments if necessary to hide teeny parts of bras or whatever that might stick out. On mine, if you looked down on me, you could see the top of my bra (not from the front, but from the top). I'm short, so this was a problem. My seamstress actually sewed a bit of velcro to my dress and the bra, so you couldn't see anything anymore! Waaaa-LA!
Also, If you have a body shaper on, or whatever, it would conceal the bag - at least enough to where it isn't hanging all out. When I told people at my gym about my issues, and then the bag was sorta visible under my workout spandex, I just told him it was a bandage appliance for a recent surgery. You could tell your seanstress something like that if she sees an outline or something. In anycase then you can feel free to put on or take off the dress in front of other people - you wouldn't actually be exposed. :)
Let me know if you want any tips - I had a pretty big wedding, and I'm happy to share what I learned! Or, if you just want to gush and rant and rave and brag and need someone to listen, I'm here. I know my family and friends got a bit sick of me after a point! LOL.
Send me an email, if you want. :)
