Leave the shyness at home. No matter what type of clothing you choose to wear, either it will be short or tight or both. Swimming is supposed to be done in such clothes. Else you will become heavy with water absorption and there will be difficulty in swimming.
Doesn’t matter if you think many people are staring at you. Because no matter how good or bad you look, people are going to stare. They got nothing better to do.
But don’t let them ruin the moment of swimming for you. Because after the swimming session is over, all of them will forget what you were wearing. But the moment of stress and fearful swimming will stay with you.
If you had to choose then why choose something which will do bad for you in the long run.
So go ahead and wear those bikinis if that pleases you and get to swimming. All of us are here for that – go get swimming.
