There are times when a person wants to post a picture of themself on Instagram but they want others to see how they look. This is probably not a good idea. There are ways to get a quality picture that shows you have a great body or are very good looking but does not show much. Just like there are ways of wearing cloths that can make you look good and leave something to the imagination, pictures work the same way.
There is nothing wrong with taking the picture or put it onto Instagram if just having the people that you want to see it seeing it. But there are so many ways that this can go wrong and the wrong person sees it. What if a clown was to see it and he wanted to show you his balloon animal?
