Remember, timeless is best. Personally, I love maxi dresses for maternity pictures. Floor or knee-length maxi dresses with chunky necklaces are incredibly flattering on a pregnant body. Moreover, prepare a few outfits to wear for your maternity shoots, such as a casual outfit, a dressy outfit, a set of lingerie, a fitted dress, and a flowy one.
Since the main focus in your maternity shoot is your bump, then don’t let anything take attention away form that, like a pattern or print. Wear solid colors for your bump to stand out the most. If you want to incorporate pattern into your shoot, have your husband wear a patterned shirt instead. If you feel solid colors are too boring, then bring in some fun, bright, and bold accessories like necklaces and scarves.
