I would say from 12 weeks to 20 weeks the growing period is very odd. By now, I can't fit in any of my jeans and sweat pants are my best friends. I'm stretching all my regular tops until I really can't fit in them comfortably.
Luckily, I've always enjoyed wearing loser-fitted clothing, so this works out in my favor. I do love a fitted dress with the pregnancy though because this is the only time we can actually let our belly hang out ladies! Own it and enjoy it!
