A new Hot Buys item is out! It's Hot Buys Triangle Cut Out Swimsuit, part of the Hot Buys 2010 April collection. Luckily, it's black so it can be matched with a dark outfit easily. It's branded Bisou and it costs 8$ - which is pretty cheap for Hot Buys items in my opinion.
Real life version? Zimmermann. It has 3 lines of cut out triangles instead of one, but I believe this is the one. Picture:
