This is one of the only bras that CAN be worn all day - which offers more convenience for a pumping mom. My only complaint is that once your milk comes in, it becomes so tight and you start falling out of it without any support or stretch to the bra. I ordered a small based on the size chart, but when I got it realized it was WAY too tight. I returned it and purchased a medium and that fits but only until I have my let down and it is way too tight as well. I also cant wear it at night - which is why I bought it, for day and night wear - because when I lay on my sides my boob hangs out of the side and I have to readjust everything and it wakes me up. I wish it was straight across the chest and not a V.
