I was reading away, and my bathing suit wasn't fitting properly and the tassels on the top of my bathing suit were getting in the way.
I too off my bathing suit top. It felt very awkward at first, but so many people around me weren't wearing clothing it didn't seem to weird. The greatest part was that my body image issues barely arose! It was an incredibly liberating experience and I was able to comfortably read and enjoy my time at the beach.
If any of you get a chance to go to a clothing optional beach, I highly recommend it. I recommend changeling your body image issues and put yourself out there. I don't regret this experience at all, and would happily do it again. I'm actually going to the beach again tonight for a swim, and will most likely go topless.
