Maternity photo shoot dress

Hello ladies! Need help, I'm looking for a dress for my photoshoot, but I can't find anything that I like 😥😥 plus I don't want to spend hundreds on the dress that I'm gonna wear only for couple hours. So where did you ladies buy your dresses?? I found one that I like, but have no idea where I can buy it or at least very similar style. Here is the picture from the internet. Thanks for any input!!
