Jennifer Lopez is a style queen. The mother of two might be regularly draped in Versace couture but she also stays smart when she's shopping. Case in point, the $42 dress she wore out in Miami last night. 

The dress, from Naked Wardrobe, one of those internet-famous boutiques that makes sexy clothes, is a bargain at $42. But we guess that J.Lo has some serious selling power because, as of this morning, the dress was out of stock. 

Lopez paired the affordable dress with pricey $950 shoes from Giuseppe Zanotti, a designer with whom she has a friendship and a capsule collection. If you're interested, those are still up for grabs.

We love a girl that shops smart. Keep checking back on Naked Wardrobe because they promised to restock soon.
