Beach goth maternity shoot?

Hello all! I’m expecting in August and we’re planning on doing a lil beach goth mat shoot in July. Our original idea was going to be like black/white stripe sort of motif, but I’m having trouble finding nice dresses that will give me enough room at the stomach. I’m only starting to show a bit now but I’m assuming that by month 8 I’ll be much bigger. I use a cute black sun hat and some giant sunglasses I’m planning to use. May get a parasol.

Open to any recommendations. I’ve been browsing La Femme en Noir and Blackwood Castle bc I’d love a reason to get a nice dress from them.
