Friday Oaks Day is the formal Ladies Day of the Epsom Derby Festival. The Queen's Stand requires morning suit for men (or formal lounge suit) and cocktail-length dress + fascinator/hat for women. The Diomed Stand requires lounge suit / smart formal.
Saturday Derby Day is more relaxed but the Queen's Stand still requires a jacket for men + formal dress for women. The other enclosures step down progressively to smart casual (Lonsdale) and festival-relaxed (General Admission).
Key 2026 changes: The Jockey Club has confirmed that the Queen's Stand admits women in trouser suits (with formal blouse) on both days from 2025 onwards, a structural update from the historical morning-suit-and-dress requirement.
This piece breaks the dress code down by enclosure across both days. For the Epsom Derby Festival 2026 hub for ticketing + access, Epsom Derby 2026 tips for race verdicts, and Epsom Derby 2026 TV guide for at-home viewing.
