Been in maternity clothing a bit for the past few weeks and am certainly starting to be noticeable (being short= bump has no where to go but out!). However, my work lab coat, which doesn't fit well over my hips at the best of times is really becoming ridiculous, and it's a bit tight across the chest too. I thought I'd sew a panel I could snap into the front so I'll be covered at work but I'm not sure how large to make it. I thought about getting a larger coat, but they aren't made for short people, so the larger it gets the lower down the chest the snaps start. How much larger around the middle did you get for those who have been pregnant before?
