The 2026 US Open takes place at Shinnecock Hills Golf Club from June 18-21 but does not operate a strict tournament-wide spectator dress code.
The championship is being staged at Shinnecock Hills in New York and the overall tone points clearly toward neat, respectful golf attire rather than beachwear, gymwear or sloppy casual clothing.
The official fan guide strongly recommends hats, comfortable shoes, cool clothing and sunscreen for conditions on site – with the safest reading being smart, comfortable golf-spectator style.
Official US Open Golf Dress Code Guidance
The official 2026 US Open guide does not publish a rigid dress-code paragraph for all fans, but it does tell attendees to dress for the weather and course conditions.
Specifically, the guide recommends hats, comfy shoes, cool clothing and sunscreen on bright, sunny days, which reflects the reality of a long outdoor walking event rather than a formal clubhouse occasion.
That means the practical baseline is simple: wear something breathable, modest, weather-appropriate and easy to walk in for hours – much as it is for the Masters and USPGA Championship in the United States.
Golf spectators commonly lean into golf-style clothing anyway, so polos, lightweight shirts, quarter-zips, skorts, dresses, chinos and tailored shorts all fit naturally – as well as potentially some waterproof if the weather turns.
What to Wear in General Admission
For most spectators, the right target is polished comfort rather than strict formality.
There is a lot of walking at the U.S. Open, and Shinnecock’s terrain plus summer heat make footwear and fabrics more important than dressing up aggressively.
Men
Good options include collared golf shirts, lightweight button-down shirts, quarter-zips, chinos, smart shorts and comfortable walking shoes.
Even where not formally required for spectators, tucked-in shirts, belts and neat presentation look most in step with the country-club setting.
Women
Women are typically well served by golf dresses, skorts and polos, neat shorts, lightweight trousers, or relaxed but polished summer dresses.
The best outfits combine breathability with practicality, especially if you will be walking the course rather than sitting in one grandstand all day.
What Works Best
- Moisture-wicking or breathable fabrics such as cotton, linen blends and performance golfwear.
- Neutral or classic colours that feel appropriate to a major championship setting.
- Sunglasses, sunscreen and a cap or brimmed hat for sun protection.
Footwear Rules & Walking Advice
Footwear is arguably the most important part of a US Open spectator outfit because patrons often walk several miles in a day.
It is recommended to wear comfortable shoes with the safest choices being clean trainers, walking shoes, golf shoes designed for spectators, loafers with grip or supportive flats.
Open-toed shoes and flip-flops are a poor fit for the course environment.
Hats, Caps & Sun Protection
Hats are explicitly recommended in the official US Open fan guide for sunny conditions.
For general spectators outside formal club spaces, caps and brimmed hats are entirely normal and practical.
The one nuance comes in the rule that gentlemen are required to remove hats on porches and in the clubhouse. So if your ticket or experience involves club-adjacent indoor areas, it is sensible to treat hat etiquette more carefully there than out on the course.
Hospitality & Premium Areas
There is no separate detailed dress code for every hospitality area, but hospitality and VIP points toward business casual or dressier smart casual in premium suites and corporate spaces.
That usually means stepping up from pure spectator wear to something more polished.
For men, that can mean long trousers or tailored shorts with a collared shirt and potentially a lightweight blazer if you are spending time in lounge-style hospitality.
For women, refined dresses, tailored trousers, elegant golfwear or polished separates all work well in premium settings.
What Not To Wear
Even without a hard public tournament-wide dress code, there are several categories of clothing that sit well outside the tone of the event.
- Denim or jeans, especially because Oakmont bans denim anywhere on club property.
- Gym clothes, jogging bottoms, leggings worn as activewear, warm-up suits and overt athletic training gear.
- Flip-flops, beach sandals or shoes unsuited to hills and long walking days.
- Offensive slogans, overly revealing clothing or anything likely to distract from the event atmosphere.
- Extremely impractical fashion choices such as heavy heels or shoes with no grip.
Packing & Bag-Policy
Dress code advice is easiest to follow when paired with the official entry rules.
For the US Open, the USGA allows clear bags up to 12 x 12 x 6 inches or smaller non-clear bags up to 6 x 6 x 6 inches, and empty reusable water bottles of up to 32 ounces are allowed if they are non-glass.
Because food and drink are otherwise restricted, and weather can shift quickly, practical extras such as sunscreen, sunglasses, a small poncho and a permitted compact bag matter almost as much as your outfit.
US Open Dress Code FAQs
Is there an official dress code for the US Open?
Not in the sense of one strict tournament-wide spectator uniform. The official fan guide focuses on practical clothing for weather and walking, recommending hats, comfortable shoes and cool clothing.
Should spectators wear golf clothes?
They do not have to, but golf-style clothing is often the easiest and most appropriate option. Polos, skorts, dresses, chinos and lightweight layers fit both the atmosphere and the practical demands of the day.
Can you wear shorts to the US Open?
Yes, smart shorts are widely worn by spectators, and Oakmont’s guest guidance itself allows shorts subject to length standards. Very short, scruffy or athletic-gym-style shorts are a worse fit for the setting.
What shoes should I wear?
Comfortable walking shoes are the top priority, and the official fan guide specifically recommends comfy shoes.
Clean trainers, supportive golf-friendly shoes and smart flats are all better choices than flip-flops or hard-to-walk-in dress shoes.
Do I need to remove my hat indoors?
On the course, hats are normal and even recommended for sun protection. In clubhouse settings, the club’s guest rules say gentlemen should remove hats.
