Help from stylish moms...

Katie
I'm really struggling with what to wear for our family's newborn photos. I have outfits picked out for our little girl but don't know what I should wear. Is like to wear something soft and feminine and not tight. Nothing too casual (jeans and t-shirt) or too dressy. I'm not worried about cost.
What are you planning to wear? Any suggestions for items I can buy online that would work?
Any and all advice is so appreciated!!!
P.S. I'm due at the end of October and my area will be in the midst of cool but not cold fall weather when she arrives.
