Hi! So today I did something way out of my comfort zone I posted a picture of myself in my bathing suit. I'm in Hawaii with my folks for vacation was posting pictures. I felt cute and I felt confident so I posted a pic. But about 20 min later I was getting messages from people saying I needed to take it down because it wasn't classy and it made them uncomfortable to see it. I was mostly covered except my legs. I dont understand how this could make someone uncomfortable. I didn't delete it but I was very hurt by this and I didn't know what to say. Does it look that bad?
