Lena from Quality Rivets went through her whole pregnancy without buying a single piece of maternity clothing. I loved the way she still kept her own style and rocked it to the end.
Of course if you haven't been following Sydney of They Daybook yet, you must! She is in the middle of her pregnancy, and totaling rocking it, and has the funniest pregnancy stories ever! I really hope I can look this good when I'm pregnant.
