These look lumpy under a bra with no cups, but they absorb plenty and I haven't ever leaked through. I wear them under a bra with cups and no one's the wiser. I've washed them a dozen times with my regular laundry and dried them in the dryer with no issues. I will say that in hindsight these aren't as necessary as I thought- I often wear a small burp cloth under my bra because it doesn't fall out as easily and that way I don't have to dig through my diaper bag to find one when I'm nursing on the go. Once I go back to work I think I will use these more because a burp cloth would look weird under professional shirts.
