This is the best blogger-recommended product I've bought this year!! It's thin at the edges and thick in the middle, so you'll never have embarrassing nipple show-through or a noticeable circle under your clothes again. Most importantly, it's super sticky but not so uncomfortable that it's overly noticeable, and it doesn't sting or pull out any fibers when you remove it! The other day I wore a strapless top to an amusement park, and in 30-degree weather I was sweating buckets, my clothes kept getting soaked, but it stayed firmly in place!!!
