maternity dress!

So my fiancé and I are expecting a beautiful baby girl due in July. We were already planning a small wedding since last February when we got engaged. Now with little Madison on the way, I want us to get married before she's here! Our new wedding date is April 1st and I'll be 26 weeks. I want to have the same last name as my husband and daughter and for us to be husband and wife before she's born. Just how I want it! But now that I will be getting married while pregnant, I'm having trouble researching a maternity wedding dress! I really don't know about buying one online because I haven't actually visited a shop to get my dress measurements yet. Any other ladies who got married while expecting? Can you help a girl out and tell me what you did/how you got your wedding dress? Pleeeeease! ☺❤
