You could wear a nursing vest underneath the jumper dress or turtle neck jumper, thatâs what I do x
Cardigans!
I bought nursing jumper dresses, nursing turtle necks and nursing vest tops from Seraphine, as I really didn't want to compromise on how I felt in my clothes it was really important to me to feel like it did before children. I got some bits in the sale and off vinted to make it more affordable and I've used the items for both my children, so doesn't feel to much of a waste of money.
Also love Seraphine and jojomaman and got a lot of the dresses second hand on eBay.
I just wear jumpers and lift up or cardigans or a nursing jumper
I'd switch it out slightly to have a nursing vest (or just regular stretchy vest) underneath a jumper and keep the rest the same. Jumper dresses would be less ok unless you're also covered on the bottom with leggings I'd say. Pull the jumper up, vest down and there you go. You can buy clips to help keep bulky jumpers up but a hair claw clip or just holding it with your hand works fine.
