Gold metal lined racks display a carefully edited selection of luxury clothing for every occasion, from daytime power lunches to nighttime cocktail hours and celebratory dinners. The Wynn Collection (really wish they had changed it) is for the ladies. Walk down the corridor off the atrium across from fine dining Italian spot Sinatra, and you’ll find four high-end boutiques with storefronts that still boast the Wynn name. No need to lay all your cards on the table: You can do some serious damage to a single plastic one at the shops at the Encore Boston Harbor.
