Hannah Davis thinks swimsuits are ''sexier'' than bikinis.

The 25-year-old model - who made a splash wearing a tiny two-piece on the cover of the 2015 Sports Illustrated Swimwear Issue - has insisted women don't need to wear a ''skimpy'' bikini to look good, and referred to the likes of Pamela Anderson's famous 'Baywatch' red swimsuit to prove her point.

Hannah said: ''I love a one-piece. I just started getting into them last year, and it's so much sexier. You are like the cool, sporty girl who isn't trying too hard. Like in 'Baywatch' - they didn't have to wear a skimpy two-piece to be hot.''

The blonde bombshell also revealed she keeps in shape by running around and playing Frisbee on the beach, but doesn't ''obsess'' over whether her figure is looking trim.

Speaking to Style.com, Hannah said: ''I am not a girl who just sits at the pool and lays out. If I go to the beach, I am going to run around like a little kid.

''I just try to stay active and do things like play Frisbee at the beach. If I obsess about it, it never works, so I feel like I am in better shape when I don't worry too much.''
