The US Open is one of the few sporting events in New York where the dress code question is genuinely interesting. Most stadium events in the city have no dress code — you wear what you wear to a game. The US Open at the USTA Billie Jean King National Tennis Center in Flushing Meadows is different: it has a tradition, a specific social character, and a clientele that spans from the casual tennis fan to the corporate hospitality guest to the serious social occasion attendee. What you wear depends entirely on which of these contexts you are in.
The Contexts at the US Open
General grounds admission. The walkabout ticket — access to the grounds and the outer courts without an assigned seat at Arthur Ashe or Louis Armstrong Stadium — is the most casual context at the US Open. Comfortable, put-together, weather-appropriate casual is entirely correct. Quality athletic or sports casual wear reads well here; there is no expectation of tailored clothing.
Reserved seating at outer courts. One step up from the grounds — a reserved seat at one of the named outer courts. Smart casual is appropriate here: quality trousers or chinos, a polo or quality button-front shirt, a blazer if the occasion is more social than sporting. The dress is still clearly sport occasion, but put-together.
Arthur Ashe Stadium seating. The main stadium, particularly in the premium seating areas, has a more social character. The corporate entertaining that happens in the premium Ashe seats — clients, colleagues, significant social relationships — creates an expectation that is closer to smart casual professional than to sports casual. A quality blazer over a polo or open-collar dress shirt reads as correctly calibrated for this context.
Corporate hospitality suites. The US Open corporate hospitality experience — the enclosed suite, the catered service, the client-entertaining context — is a professional social occasion that happens to have tennis outside the window. The dress code is the same as a client dinner or a professional social event: smart casual to business casual. A blazer and quality trouser with a dress shirt or polo is the correct standard.
The Chairman's Room and premium social spaces. The US Open's highest-tier social spaces are genuinely formal — dinner jacket level for certain evening events, smart formal for others. These are event-specific, and the invitation will typically specify.
What to Wear: By Context
Day session, outer courts or grounds: Quality chinos or trousers in a neutral (navy, tan, stone), a quality polo or Oxford shirt, clean leather sneakers or loafers, a light jacket or quality sport casual layer. Comfortable but put-together.
Day session, Arthur Ashe or Armstrong reserved seating: A blazer over a polo or open-collar dress shirt with quality trousers. A loafer or clean leather sneaker. The blazer — even in a linen or lightweight fabric for summer — elevates the outfit to the social occasion level without over-formalizing a daytime sporting event.
Evening session, Ashe premium or corporate: A quality blazer (linen or lightweight summer cloth), dress shirt or polished polo, tailored trousers, leather shoe. This reads as smart casual professional and is appropriate for both the sporting context and the client-facing social context of corporate hospitality.
Corporate hospitality suite: Business casual to smart casual. A blazer is expected; an open-collar dress shirt or quality polo underneath. Quality trouser; leather loafer or oxford. For women: a blazer with tailored trousers or a quality smart casual dress. The context is professional entertaining with a sporting backdrop — dress accordingly.
The Summer Fabric Question
The US Open runs through August and early September in New York — historically the city's most humid period. The fabric choices for the US Open are more constrained by climate than by formality level.
Linen. A linen blazer in navy or stone is the single most appropriate choice for a blazer at the US Open. It breathes in a way that wool cannot in August in Queens, and the slightly relaxed texture of linen is calibrated to the sporting social occasion rather than the office. The wrinkling of linen, which is often cited as its disadvantage, reads as characteristic rather than sloppy in this context.
Lightweight cotton. A quality cotton Oxford shirt or a lightweight cotton trouser is the practical foundation for most US Open outfits. Cotton breathes and washes easily — important for an outdoor event in summer heat.
Tropical wool or wool-silk blend. For the corporate hospitality or elevated evening context: a lightweight Vestium NY commission in a CARNET wool-silk or a Holland & Sherry tropical wool — at 7–8oz — is appropriate and significantly more comfortable than a standard suiting weight in August heat.
What to avoid: Heavy wool suiting (8oz and above) is too warm for a full day in the summer sun at Flushing Meadows. Dark colors absorb heat; lighter neutrals (stone, tan, light grey, pale blue) are more practical.
For Women
The US Open's social character is slightly more permissive for women in terms of range — the spectrum from quality athletic wear (outer courts, casual sessions) to smart casual (premium seating, corporate) to summer formal (evening events, Chairman's Room) is wider and each step is well-established.
Outer courts/casual: Quality athletic or sport casual wear; a quality sundress in the appropriate formality register.
Premium seating/corporate: A tailored blazer with quality trousers or a midi dress in a summer fabric. A linen or cotton blazer is appropriate and practical for daytime sessions.
Evening/elevated: A tailored summer suit in a lightweight cloth; a smart formal dress; a quality blazer with a wide-leg trouser in a summer weight.

The consultation for a summer weight piece covers the specific occasions it needs to cover, from the Open to September gallery events to early-fall professional occasions.

Frequently Asked Questions
Is there a dress code at the US Open?
No enforced general dress code, but the social context of the specific ticket or hospitality arrangement creates real expectations. Corporate hospitality and premium suite guests are expected to be smart casual to business casual; general admission has no specific standard.
Can you wear a suit to the US Open?
A full business suit is over-formal for most US Open contexts and also impractical in August heat. A blazer and quality trouser — particularly in summer fabrics — is the calibrated choice for premium and corporate contexts.
What shoes work at the US Open?
Leather loafers or clean leather sneakers for casual to smart casual contexts. A leather oxford or derby for corporate hospitality. Comfort matters for the amount of walking involved at the Billie Jean King grounds; a quality loafer is the most practical balance of appropriate and comfortable.
What is the dress standard at the US Open Chairman's Room?
The Chairman's Room is one of the most elevated social spaces at the US Open — the dress standard is smart formal to formal. A jacket is expected for men; equivalent standard for women. The specific event and invitation will indicate if black tie is expected.
When should a US Open wardrobe be commissioned?
Summer weight pieces should be commissioned in spring — May at the latest for an August Open attendance — to allow the standard 5–6 week production timeline.
