Overview and Quick Guidance
The Cannes Lions International Festival of Creativity dress code is business‑casual to smart‑casual for most conference and exhibition days, with semi‑formal or optional formal attire for main stage events and awards evenings. The festival emphasizes inclusivity, comfort for long days, and weather‑ready fabrics, avoiding overly beachy or overly casual items. For men, this typically means chinos or smart trousers, collared shirts or polos, and closed shoes; for women, tailored trousers or skirts, blouses or smart knitwear, and comfortable yet polished shoes. Always defer to specific session invitations, venue signage, and the latest guidance from Cannes Lions organizers.
- Business‑casual is the default for conference and exhibition halls.
- Semi‑formal or optional formal for main stage and awards events.
- Consider heat, crowd comfort, and respectful attire for diverse audiences.
What Business‑Casual Means at Cannes Lions
Business‑casual at Cannes Lions balances professionalism with the practical realities of a summer festival environment. Attendees should aim for polished but breathable pieces that work across meetings, pitches, and exhibition floors. The goal is to look prepared and respectful while moving between venues, often in warm weather and crowded spaces.
For Men
Men can wear lightweight chinos or smart trousers, long‑sleeve or short‑sleeve collared shirts, and optional blazers for more formal sessions. Polo shirts are generally acceptable when paired with tailored shorts or trousers. Footwear should be closed‑toe shoes or clean sneakers suitable for walking. Sandals, overly distressed denim, and sportswear are best reserved for off‑hours.
For Women
Women can choose tailored trousers, midi skirts, or smart casual dresses with breathable fabrics. Blouses, smart knitwear, and lightweight layers work well for air‑conditioned indoor spaces and warmer outdoor settings. Heels are acceptable for evening events if you can manage uneven venue surfaces, while flat sandals or low block heels are practical for daytime. Avoid beachwear, overly casual athleisure, and slouchy beach cover‑ups in conference areas.
Semi‑Formal and Optional Formal Events
Certain main‑stage keynotes, industry panels, and awards evenings may request semi‑formal or optional formal attire. This is particularly true for gala dinners, sponsored receptions, and closing ceremonies where photography and visibility are higher.
Men’s Options
For semi‑formal moments, consider a dark suit or a well‑fitted blazer with dress trousers, a collared shirt, and a tasteful tie when needed. Leather shoes should be polished. In warmer weather, a lightweight suit or a blazer with chinos can keep you comfortable while maintaining a refined appearance.
Women’s Options
Women can opt for a tailored dress, a coordinated separates outfit (blazer and dress pants or skirt), or an elegant evening gown suitable for sitting and moving through events. Fabrics that breathe, modest hemlines for ease of walking, and comfortable heels or flats are recommended. Evening events may allow for bolder accessories, while daytime formal moments favor clarity and mobility.
Practical Considerations and What to Avoid
Cannes in June can be hot and humid, so prioritize breathable fabrics like cotton, linen blends, and lightweight wool. Expect long walks between venues, security checks, and crowded exhibition halls, so choose footwear that supports extended standing. Beachwear, overly casual sportswear, and attire that restricts movement can create uncomfortable moments or give an unintentionally casual impression in formal settings.
- Choose breathable, lightweight fabrics.
- Plan for comfortable walking and extended periods on your feet.
- Follow specific invitations and venue signage when in doubt.

Weather, Comfort, and Venue Logistics
June in Cannes brings warm temperatures, humidity, and frequent sunshine. Venues span historic buildings, modern conference centers, and open outdoor spaces, each with varying air‑conditioning and seating. Layers can help you move from sunny outdoor queues to cool indoor theaters. Pack a light blazer or cardigan, comfortable shoes, and a compact umbrella for occasional showers.
Final Guidance and When to Confirm
For most attendees, business‑casual with the option to elevate to semi‑formal for specific evenings will cover the Cannes Lions schedule. Confirm expectations by reviewing session‑specific invitations, the Cannes Lions app, and any communications from your agency or clients. When in doubt, lean slightly more polished; organizers typically provide clear notes if a particular event requires formal attire.
