My est due date (based on last period) is October 17th. I'm in a wedding August 20th and I have to order a bridesmaid dress this month sometime! It's my first baby so I have no idea what to expect. I'm typically a size 6, when I was measured for the dress a few weeks ago they said my waist is an 8 and my chest is a 4 (they recommended going with a 6). I know I have to go bigger and get it tailored but I just don't know how big?! It's an Alfred Angelo dress, photo is below....
