We love Rachel Bilson's California cool style. This look is all about the layers. We've broken down Rachel Bilson's look so that you can be just as trendy and hip while you're pregnant. Colored denim hit the scene last year, but they will continue to be popular through the summer. Stay on trend with the Maternal America Plum Skinny Ankle Jean. This colored maternity jean looks great with heels, flats or suede booties just like Rachel was wearing. The Isabella Oliver White Scoop Top is the perfect layering piece. Complete this look with a fitted blazer and a scarf in a fun print.
