Layering pieces are key when the weather is cool. I stay warm and my outfit remains nursing friendly. I would recommend buying your layering pieces in neutral colours so that you can pair them with practically any outfit.
I bought this black cardigan from the Me-To-We company several years ago. I wear it several times a week and it still looks brand new! The quality has been superb! All of their items are ethically made so it is a purchase that you can feel good about.
I bought this jacket on a super sale at Reitman's a couple years ago. It has also proven to be a staple in my closet and it has been a quality piece, as well.
