So I went on a fabric search. Sadly, my local stores are lacking and I was not even going to try to match whites online (I already had the lace in my stash). So........compromises were made. I really did want a sweatshirt fabric for the main shirt but ended up with a heavy ponteroma fabric instead.
I used the Sewaholic renfrew pattern. At first, I tried to leave the bottom band off and add side vents like the picture but the fabric is so stiff that it just hung off my chest making me look 9 months pregnant. Not good! So I cut the bottom hem off and added the renfrew hem band and ended up loving it. The fabric drape is not perfect but I still love it.
I am still on the look out for some great cream colored sweatshirt fabric but for now I will happy wear this one.
