Molly Sims is six months into her pregnancy, but the mom-to-be still avoids maternity clothes when she can, preferring to showcase her baby bump in tight-fitting outfits. "I'm stuffed in. This isn't maternity, so I somehow miraculously fit," Sims told us of her Valentino gown at the opening of the label's Rodeo Drive store. "The tighter the clothes are around your belly, the smaller you look, in a weird sort of way," she said. When the Project Accessory host isn't working designer gowns, she dresses for two in stretchy jersey separates. "I love Rachel Pally at the moment," she told InStyle.com. "She gives you color and a little bit of chicness. I'm loving the long boho skirts and fun blouses." Click through the gallery to see more of Hollywood's most stylish moms-to-be!
