The 25th anniversary of The Wall Group, Brooke Wall’s styling agency, celebrated with a party at Delilah. The party was a reflection of how much has changed since Wall started the agency in 2000, when stylists had lower profiles, fewer clients and less leverage. The agency, which was sold to WME in 2015, represents many of the biggest names in hair, makeup and styling and its agents are now involved in far more than simple bookings. The evolution of celebrity styling has led to a more polished, more strategic, more tightly branded world dominated by major luxury houses.
