Comfort is key during pregnancy, so if you're trucking to the office every day, then you need to find a wardrobe solution that's easy to wear and looks pulled-together, i.e. a sweater dress. Our favorites this season all come in shades of navy. Topshop's rib-knit dress ($57) comes in a cool shade of indigo. ASOS's knitted striped dress ($62) is perfect with tights and ankle boots. Gap's rib-sleeve dress ($55) has gray-and-navy stripes.
