I made a couple of the Hotpatterns Cosmopolitan Dresses last year and I knew they would be perfect for breastfeeding as the wrap goes the whole way across the dress. Because they are made from stretchy fabric they are also perfect for those of us who don't immediately lose that post pregnancy stomach (I still haven't lost mine after having the twins 7 1/2 years ago).
I love this fabric from Spotlight. Yes it is polyester, but it is pretty soft and I love the colour and it was on special. I can't remember for how much, but this was a pretty inexpensive dress. I think I managed to get it out of 1.8m. I left off the tie as it just drew attention to my stomach and I used the short sleeve from Simplicity 3775. I also added a band around the neckline as before. I cut it 2 1/4" wide, but would make it even thinner next time.
I have already cut out Butterick 4914. It is very similar to Simplicity 3775, but when I compared all the pattern pieces, the tops are quite different, so I thought I would try it and see what it is like.
