I would absolutely take that opportunity if it was anything besides a fantasy. The biggest problem with wearing a baby bump is the time frames and the expectations (pun intended) of others about you having a child and when. not to mention the societal expectations about what expecting moms should and shouldn’t be doing.
If you were to ‘bump’ yourself I would imagine that you would have to keep it to postpartum size or smaller to avoid the “when are you due?” conversations. About the size where someone doesn’t want to say anything as you might just be a bigger girl.
My 2 cents.
