I am pregnant and was looking for some comfortable breathable bras without underwire or boning. I was hoping they would be stretchy enough to accommodate my constantly changing body. The low price was important, I didn't want to spend a ton of money on something I might only wear for a few months. I felt the bras were true to size, and I bought them a little bigger than I currently need.  They are breathable, no pinching or chafing. I think they would be great for breastfeeding and post-delivery sleeping. The bras do not have itchy tags (a pro), but  the strap length is not adjustable (a con). I am generally happy with this purchase, but only because it fits my very particular needs. I would not recommend these bras for sports or if you are on a bigger side, they offer very little support. They might work for yoga, but not for jogging. My current size is 38D, and size 38 fits me well, it is even slightly big, which I was planning for.
