Fortunately from what I saw thong bikinis aren't trending in 2012. I think you will find many women wearing them. They do not suit your average woman so the fashion industry won't be trending those because they don't sell well.
I mean you could consider a mens swim thong to be a thong bikini. I mean they do have bikini brief mens swimwear. Anyhow. I rock the man thong at the beach. I love to sun my buns. And i love the freedom i get when wearing them. I dont see why more men and women do it more often.
Well strictly speaking we don't have a beach here where I live so there's no reason for me to buy swimsuits so when I go on holiday to somewhere with a beach, I usually just wear whatever swimsuit I already have. But even if I was going to buy a brand new one, I would just buy regular bikinis - I just think they look better than thong ones.
