The new "it" swimsuits contain so many details ranging from animal pattern to sequins and belts. It is much more fashionable than just two little piece of fabric.
Will you take a risk of ruinning those "it" swimsuits by actually swim with them? Or just enjoy the sun and cocktails as if a sophisicated woman. It's your choice.
