Query: Too thick, visible under clothing

I did not like these pads at all. They are too thick, and unflattering under clothing. Also, some were saying that thick is good because it absorbs better, but there are thinner ones that absorb just as well! The medela are the thinnest and my personal favorite. Next best are the lansinoh, a little thicker but still doable...these are my least favorite.
