Rim a chilled martini glass with lime juice, then dip the rim in pink sanding sugar.

Add the Malibu Pink, citrus vodka, triple sec, fresh lime juice, and cranberry juice to a shaker tin.

Fill the shaker with ice and shake vigorously until well chilled.

Double strain into the prepared martini glass.

For the garnish, cut thin wheels of both a lime and an orange. Cut each wheel in half, then overlap the two lime halves to form a flower shape. Repeat with the orange halves, layering them behind the lime. Secure both with a heart-shaped cocktail pick and place the garnish on the rim of the glass.
