It's hard to tell from just one pic, but I can say I don't imagine many people would give that chest a second glance at the beach, judging by that one picture. At close inspection I can almost see a bit of a buldge on the right side, but it's very minor in that shot.
Do you have an issue with T-shirts or with the general feel of your chest? If not I would honestly suggest you don't worry about it. It may take more pics, but judging on that one you look well in the range of normality to me.
Cheers.
