Very comfortable, with quite good support. I would like it to have more cotton in its composition, so it would be cooler in the summer, but okay. The bralette does not show under white t-shirts, but at the cups, because it does not have padding inside, the nipple shows through. So, I don't wear it with white t-shirts. Well, you can't have everything. If it had padding, it would be warmer. In general though, I would buy it again.
