It depends on what YOU prefer and how you feel in the suits. I, personally, don't like tankinis on me but I do like two pieces and one pieces, but like the shorts kind. (Know what I mean?) Lol the Marilyn Monroe type.
But it just depends on how comfortable you are in the bathing suit.
My girlfriends pretty chubby and she wears a bikini, no one cares
Really depends on the suit and the body. My advice is to try on both types of suits to see what works best for you.

Actually, the one in which YOU feel more comfortable will look more attractive because you'll be confident and sexy. If you look FANTASTIC in the bikini but are not comfortable and confident wearing it, then guys won't look at you the same way as they would if you wore something that made you FEEL sexy, confident, and dignified.
