What to Wear:

Our entire operation is quite informal, and this informality extends to the Gardiner office. Male employees are expected to be neatly and presentably dressed, but this definitely does not mean a coat and tie. Open neck sports shirts and slacks are quite appropriate for office wear. Female employees may wear summer-type dresses, skirts or slacks and blouses. Blue jeans and T-shirts with slogans are not considered appropriate office apparel for either male or female employees.
