I'm currently wearing my panache purple silky nursing bra, which I find a little bit tight after a full day but very pretty. Then I have a white one from M&S with a bit of lace that's quite nice, good shape not granny. And my white and red lacey Hot Milk one which is perfect in everyway.
I had two nightbras which I wore till Silas was 7 months old, with nursing pads (saved me soaking the place) they were dead comfy, got them from mothercare and would recommend. Then the two frumpy M&S ones which literally wore out. After a year the only place they were good for was the bin!
So I only have 3 bras really! I have a couple of nice non-maternity ones for the evening if I feel like it or I'm going out, but generally I've been wireless for at least 18 months now!
