Freya Swim Madame Butterfly Underwire Bandeau Tankini Style 3493. The Madame Butterfly underwire bandeau tankini top is more flirty than fluttery. Madame butterfly gives you a strong look. With its bold graphic prints scattered across a vibrant base this keyhole opening with a connected soft tie around the neck gives this sweet looking print wing to really make it fly pass sexy expectations. For support and lift the top has a built in underwire. But for comfort it has a bandeau style neckline that goes back into a clasp for support. This bikini top is also available in prints by Freya Swim.
