depends on what I have on. If I am going to work no because I wear yoga pants and dont like underwear lines....or I will wear a thong. If I am wearing jeans it just depends on my mood.
When I wear boardshorts, no. If I'm wearing jeans or regular shorts I'll usually wear a thong, sometimes a string bikini.
Underpants yes if wearing pants. I stopped wearing bra 3 months ago and I've never felt so free on my chest I was worried about someone seeing that I am not wearing anything under shirts but no one noticed anything. that was one of the best decisions I've made lately free the boobs ladies.
