'We Can't Stop' talking about Miley Cyrus' ever-evolving style. Some days she's on. Some days she's off. But she was on like Donkey Kong in this vintage black Versace creation in Miami at the iHeartRadio Ultimate Pool Party this weekend. The cage-like construction and choker collar, complete with gold hardware, were sturdy and sexy. The dress looked heavy, but she made it work.

The singer, last seen in NYC with a flat comb-over, returned to her punk-pop pompadour. While it's hot and humid in Miami, it's a sexy city and she needed a big 'do to match her bodacious dress.

Smoldering stare. Shoulders back. Skin that's incredibly shimmery and dewy. Jeez, Miss Miley was hotter than the sun.

Look at those legs! Cyrus has some serious stems.

The dress is a bit dominatrixy, but she pulled it off without ever looking vulgar or trashy. A nice rebound from some of her recent ensembs -- cough, sweatpants jeans, cough.

Once more ... with feeling. But why so serious?
