mamas I need advice. I'm changing my baby shower outfit because I can't wear dresses. I just don't sit with my legs closed, especially with SPD it helps when I spread my hips apart, so I can't where a dress. I was thinking this top with black leggings and sandals but I'm not sure? What are your thoughts? My baby shower is April 9th from 2-6pm if that helps. *Another picture in comments*
