Wear whatever makes you comfortable sweetheart! I am also fat, and happy with my body despite butthead people bullying me, I have learnt their opinion doesn't matter - they don't really care about me. I bought a two piece bikini from forever21+ last year, and another this year, and I love them to death. I used to wear those types of bathing suits too because that's just what I was comfortable in, but now I'm comfortable in bikinis - high waisted ones. Maybe one day I will be comfortable in hipster bikini bottoms, but I am not focused on what other people find attractive, only what I am comfortable wearing and like on my body.
You are beautiful, all bodies are beautiful! Wear what you are comfortable wearing.
Fat is different from obese or overweight. I bet what you consider fat isn't fat at all. You're probably average But either way, I've never seen an obese person in a swimsuit, and I never want to. Overweight is fine with tankinis and maybe that "dress" above. If you're overweight, anything that covers the stomach is good. However, if you're obese... Don't try. It won't look good.
They are.. Interesting, though I'm not sure if the skirt detail would actually flatter your figure if you're already overweight. I'd probably go with something like a classic swimsuit, monokini or a bikini with high waisted bottoms instead.
I think they are okey, maybe not the prettiest ones. But I think there is nothing bad with cover in a little more if you aren't very slim. Nothing bad with covering a slim body either. Just see what you feel best in. :) go girl
