I don't want to go on and on about my guidelines for maternity dressing, but third pieces are key. Third pieces are essentially light jackets--blazers, leather jackets, knit jackets, etc. You can wear them (open) with any size of pregnancy AND pre/post baby, so I feel comfortable investing in them any time of year. These photos are from springtime when I was early in my pregnancy but I wore the jacket yesterday, six months into carrying this baby. In fact, my non-pregnant friend wore the exact same outfit (photo evidence here)--so she's bought into third pieces, as well.
