What details do you look for in good denim? Like most women, my favorites are any styles that make my butt look ridiculously good. Replay’s upcoming line of jeans don’t seem to care much about that. Their new collection called “Social Denim” comes with Facebook and Twitter capabilities built right in. Due to hit stores in December, the jeans feature an extra fifth pocket that contains a Bluetooth-connected transmitter. Pair the device with a smartphone and you can use one of a series of buttons to broadcast your mood and/or current location instantly. So the question becomes, what’s on your butt’s mind?
