I have been very pleased with the narrow bootleg black track pants, and tank tops with the horizontal access panel across the front - both very comfortable. So pleased, I placed a second order for another set once bubba arrived so that one pair of trousers are for wearing, the other for washing. During the early weeks of breast feeding I was wearing the tank top to sleep in at night as it provides two layers of semi-support during the night, and easy to open up in the dark. One suggestion I would have is to increase the cotton component of these tops so that they breathe better. As a new breast feeding mum I tend to 'sleep hot' what with expanding boobs, etc and the tops with high viscose/synthetics don't breathe very well, and get a bit sweaty. A cotton blend fabric would make ideal nightwear, to couple with the trousers or with other pyjama bottoms. They might also then wash/wear better over time without pilling. Just an idea - to increase your range to include sleepwear. Thanks.
