Great boutique with awesome brands. Vegas is pretty much devoid of good independent retailers. All we have is Saks, Niemans, and Nordstrom.
I pretty much did most of my shopping in LA... until I found Vasari. They are predominately a shop for women but have a great selection of casual apparel for men... jeans, shirts, t-shirts, jackets, etc. A solid stable of edgy/ trendy brands. They obviously have great buyers who have their finger on the pulse of fashion.
They are conveniently located in Tivoli Village in Summerlin near where I live.
Ardi the owner is awesome... he knows his inventory and makes great suggestions.
