I'm not plus size - I'm a size 14, 5'8" - but I don't wear a bikini. I'm going on a beach holiday in a few weeks, a proper white sandy beaches, luxury hotel, all-inclusive, holiday-of-a-lifetime kind of thing, and I thought, this is it, I'm going to wear a bikini. I know women of all sizes wear bikinis and all power to them, and I'm going to do it too.
So today I went and tried on a variety of bikinis. Patterned, plain, halterneck, fold over briefs, tie side briefs. And I have decided, conclusively, that I do not wear bikinis. I like my figure, I don't like my wobbly belly and I feel better when it is under restraint.
Not exactly an answer to your question, sorry. But you know, I do feel fairly confident about my body. I just feel more confident with a little extra support around my midriff
