I have noticed my belly expanding as my clothes are getting a little tighter and I often notice in the afternoons/evenings my belly is especially big with bloat. I am a little self-conscious about this gut I'm getting since it's not actually a baby belly yet. I want to cover it up, but as you heard I had issues with my boss thinking I had a baby belly when I didn't. I haven't told anyone at work the big news and I'm having trouble finding clothes that hide my belly without me looking frumpy. I decided to write into my favorite fashion blog, Sensibly Styled and see what they recommended I wear. They had lots of good comments. One commenter wrote a few posts on her own blog, The Moncurs, about dressing for pregnancy that are quite helpful as well.

Since my office has the A/C on high and I'm always freezing inside and sweating outside, I've decided to wear jackets to make myself look a little more professional. This draws attention away from the fact that I am wearing a more casual, loose fitting shirt. They also highly recommended Bella Bands, but many said that they are quite pricey. I haven't ever shopped for one so I'll have to see, but it might be worth it since I'm planning on having more than one baby and can reuse it. Using rubber bands or hair ties are also recommended to loosen up pants by looping it through the button hole and onto the button then wearing a long shirt to cover it up.
A lot of them talked about wearing casual clothes, which haven't become a problem for me yet since I have a lot of casual flowy shirts I bought at H&M, plus while I'm at home I'm not too worried about keeping up appearances. I'm really looking for more ideas on clothes I can wear to work. I think dresses are probably a good way to go, but I really prefer pants. Luckily I kept some fat pants from last year I bought right before I went on a diet and lost 15 lbs. I figured they would come in hand when I was pregnant and they are practically new.

Good luck! In a matter of a few weeks, you'll begin looking pregnant and you won't feel frumpy/fat...you'll feel pregnant! :)
