Pregnancy may give mama a new glow, but the early stages aren't always the most comfortable. Just one week after announcing her pregnancy and engagement, Natalie Portman presented at the People's Choice Awards, covering her belly with a tiered Jason Wu mini. The loose-fitting dress is a great choice for new mamas-to-be who are still battling waves of nausea and don't want to feel constricted by a more form-fitting frock. Best of all, the popular style is available in both maternity and nonmaternity versions, giving expectant women plenty of options! Among my favorite are Fierce Mamas by Christian Siriano's Moody Mamas Maternity "Natalie" Tiered Knit Dress ($110), Lc Lauren Conrad's tiered embellished dress ($60), Kookai Ruffle Tiered Mini Silk Dress ($95), and Ann Taylor Loft's Tiered Mini Dress ($120).
