I normally wear a UK size 10 so I went for the small, which was a perfect fit. With its stretchy material it felt like a glove and comfortable when your milk has come in and you have very sore boobs!
As soon as it's washed, its the first top I reach for as it’s the most practical top for breastfeeding. If you are planning on breastfeeding then I would recommend buying a few of these so you are not like me and waiting for it to come back through the wash again! Momzelle also sell nursing bras, accessories and have even designed clothing suitable for both pregnancy and nursing so you can make the most out of them. The MIA Nursing top is £31.50. For the amount of use I am getting from mine, it is certainly value for money.
