I know it's called "Fashion Show" and it has no shortage of high-end shops, but this is the closest you will get to your hometown mall while staying in the strip. I found myself needing to buy socks and a shirt, for reasons that are none of your concern, but most options around seemed ultra high-end, designer stuff, but I was able to get a more reasonably-priced shirt at Macy's and socks from one of the athletic shoe stores.
Nice mall too, great place to get your walk on indoors with AC and no cigarette smoke.
I forgot them, okay, I didn't pack any socks, is that what you wanted to hear? STOP PRESSURING ME, GEEZ!
