LA is the place to come for the latest styles from high fashion to street bargains. And where you go depends on what you want. If you've got plenty of cash check out Macys, Downtown. Or alternatively venture on to the Fashion District to hunt for a bargain.
The shopping mall on Hollywood has a range of shops, from mainstream clothes stores to cult horror souvenirs to alternative fashion. Along the main stretch of Hollywood Boulevard itself, there are few places worth checking out. If you've ever wanted an alternative persona try Hollywood Costumes
and Wigs. There's also a specialist Movie poster store and a Film bookshop amongst all the souvenir shops. Closeby on Sunset Boulevard is Amoeba, a huge music and movie shop with a large secondhand section. Be prepared to be seriously tempted.
Further afield is Melrose in west LA. Trendy boutiques line either side of the street interspersed with the occasional alternative rock/goth clothes shop. And the clothes will likely be a little cheaper than the same brands in the shopping malls.
