Hey Cupcake! Pinup Photography specializes in vintage boudoir and pin-up shots, but also offers maternity photography that is far from the typical hand-over-the-heart, kiss-and-smile bit. The business is located in downtown Des Moines, Iowa, so swing by if you're in the area!
I personally am a HUGE fan of boudoir sessions, and can think of no better way to feel super smokin' while pregnant. These are awesome!
