Apparently. GQ singles out Vegas for a spank in its worst-dressed cities list:
Las Vegas is known as a place people go to behave badly. But it should also be known as a place people go to dress badly. Think: Elvis in his blue (pill) period. This air-conditioned Mecca of unsustainability is the ground zero for white Midwesterners de-boarding the plane dressed in Phil Mickelson-esque pleats, tucked polos and visors and leaving the hotel in more gold jewelry than a Saudi oil baron on a junket in Dubai. The only sure bet in Vegas is that it's never going to run out of three things: hookers, hair gel, and dads wearing square-toed shoes with boot cut jeans and untucked, loudly patterned "Saturday Night" shirts.
