Here are a few similar options to what I wore in my modest maternity boudoir photos.
I have had the robe and bra since our wedding almost 10 years ago, lolz. I did get the bra from aerie & the robe from target though so they seem to be newer versions with a few other options too.
The robe is also the only thing that I wore in the hospital after delivery so that is already ready to go into the hospital bag for baby boys delivery too.
