Honestly, at work, I wear loose fitting maternity clothing as I do not want to bring attention to my pregnancy at this time. When I am not at work, out comes the belly. Anything with an empire cut or a belt with a tie in the back is going to show off the belly. Other things, IMO, make someone in the first 2 trimesters look as if they MIGHT be PG but you aren't quite sure. If I wear an oversized regular t-shirt, you cannot tell I am PG at all and I am 17 weeks tomorrow.
