The Stewards' Enclosure is also known for a strict enforcement of its dress code. Men are required to wear a "lounge suit, blazer and flannels, or evening dress, and a tie". Women are required to wear a dress or skirt that covers their knees, and are "encouraged to wear a hat" (although women wearing hats is often frowned upon in higher rowing circles). Anyone not suitably dressed can be refused entry, no matter their prestige in rowing or elsewhere. Mobile phone use is also prohibited.
