I need a costume quick fix?

I am dressing as Marilyn Monroe for halloween, and I just bought my costume. I tried everything on and it fits very well and I look great. However I can’t wear a bra in the dress. I am quite comfortable with not wearing a bra, I got to goods, but you can see the goods through the dress.
What can I use to conceal my bits without compromising my cosutme?
I was thinking of using those large square shaped bandages that are flesh colored and putting them over my nipples….
