When we first choose to do Maternity photoshoots, theres so many styles to choose from. By organising a studio Maternity closet you can provide your clients with that added service, and it also helps keep your images all within your set style. To keep costs to a minimum you may want to start with asking clients to bring underwear, you can purchase smaller items like crop tops, maternity bodysuits & light weight robes which you can get from normal online clothes suppliers. I use quite a few from Asos , Boo hoo and Zara.
