Maternity dress for photoshoot!

Hey ladies,

Do y’all have idea where can I buy maternity dress for small women? My pre-pregnancy size was XS. I have gained weight but it’s all belly. I ordered some maternity XS pants and that was a failure. They fit good around waist but everything else is loose. I gave up 🙇🏽‍♀️ I will be 28 weeks this week. I don’t plan on doing photoshoot until 36 weeks. My belly is growing everyday but nothing else has grown. I want to start looking for dresses. Thank you all 😊
