I'm still in my nursing vest tops long after I've finished breastfeeding and unsurprisingly they're on their way out.
I would like perhaps some vest tops with a hidden support but that actually fit my big boobs (34HH) or perhaps a soft bra bit so far in all my years of bra wearing I've not found any non wired bras I like.
I've seen bravissimo do sleep vests with support but a bit out of my price range really!
