I only purchased 2-3 actual maternity clothes, thus most of the clothes I wore were adapted to fit my growing body. I carried fairly small, and had a very healthy pregnancy - Praise the Lord! I wore heels, sheer tops, and body conscious clothes all throughout my pregnancy.
The pictures are separated by month, starting at Month 5, as prior to that, I could button all of my non-maternity pants very comfortably. I didn't link the photos below to the actual posts below, but all of my pregnant photos on my main blog page have the tag "PG Style". Peace.
