HOW TO GET FOUR TOPSY TURVY LOOKS FROM YOUR COSSIE

UPSIDE DOWN

ROTATE the bikini so the top of the triangles face the floor. Now tie what would be the neck strap around your back and the under-bust strap around your neck to create a gathered scoop neckline. This is great for lifting a bigger bust.

SCOOP CROSS NECK

BEGIN the same way as you would to create an upside-down scoop neck style (left), but before you tie the neck straps, layer one over the other in a cross shape, then fasten securely. This gives you more control over how much of your cleavage is revealed.
