What to Wear to a Cambridge May Ball

Understanding the Dress Code

Every May Ball specifies a dress code on its tickets and website. The vast majority of Cambridge balls require black tie. A small number — notably Peterhouse and Magdalene — specify white tie. Others like St John's are black tie with white tie optional. A few smaller events, particularly June Events and soirees, may allow smart formal or cocktail attire, though this is less common.

The dress code is enforced at the gate. While most balls are not extremely strict (nobody is going to measure your lapels), turning up in jeans and a shirt will get you turned away. When in doubt, err on the side of more formal.

Black Tie - Men

Black tie is the standard dress code for most May Balls. Here is what it means in practice:

• Dinner jacket (tuxedo) - single or double-breasted, in black or midnight blue. Peak or shawl lapels in satin or grosgrain. Avoid novelty colours unless you are very confident.
• Trousers - matching black trousers with a single satin stripe down the outside leg (though plain black trousers are perfectly fine).
• Shirt - a white formal dress shirt. A marcella (pique) front is traditional for black tie, but a plain white shirt is absolutely acceptable. Wing collar or turn-down collar are both fine.
• Bow tie - black, self-tie or pre-tied. Self-tie looks better and is more traditional, but nobody will judge you for pre-tied. Avoid novelty bow ties.
• Shoes - black Oxford shoes, patent leather if you have them. In practice, any clean black leather shoes will do. Prioritise comfort - you will be standing for nine hours.
• Cummerbund or waistcoat - optional but traditional. A black cummerbund is the classic choice. A black or dark waistcoat is also acceptable.

A well-fitting dark suit with a white shirt and black bow tie will get you through the door at almost any black tie event, even if it's not technically correct. Fit matters far more than formality.

White Tie - Men

White tie is the most formal Western dress code. Only a handful of Cambridge balls require it. If your ball specifies white tie, here is what you need:

• Tailcoat - a black dress coat with tails, satin-faced lapels. This is the defining garment.
• White waistcoat - low-cut, in white marcella (pique) cotton. This is what makes it "white tie."
• White bow tie - self-tie, in the same marcella fabric as the waistcoat.
• Wing collar shirt - white, with a stiff marcella front and single or double cuffs.
• Black trousers - with double satin stripes down the outside seam.
• Patent leather shoes - traditional for white tie, though any polished black Oxfords will do.

White tie is expensive to buy outright, so most people hire. See the budget section below for hire options.

Important: if a ball specifies white tie, you can still wear black tie. The dress code is a minimum level of formality - white tie means "at least black tie, ideally white tie." You will not be turned away for wearing a dinner jacket to a white tie ball, though you may feel slightly underdressed.

Women's Formalwear

Women's dress codes at May Balls are less rigidly defined than men's, which gives you more creative freedom but can also make the decision harder.

Black Tie

• Floor-length gown - the classic choice. Any colour, any style.
• Cocktail dress - a knee-length or midi formal dress. This is perfectly acceptable at black tie events, though you may feel slightly more casual than those in full-length gowns.
• Formal jumpsuit or trouser suit - a stylish option that has become increasingly popular at May Balls. Has the added bonus of being more practical for dodgems and fairground rides.
• Separates - a formal skirt or trousers with an elegant top can work well.

White Tie

For white tie events, a floor-length gown is the traditional expectation. Cocktail dresses can work but a full-length dress is more appropriate for the formality level.

Practical Considerations

• Shoes - this is the single most important decision. You will be on your feet for up to nine hours, on grass, gravel, and cobblestones. Stilettos will sink into the lawn and leave you in agony by midnight. Block heels, wedges, or elegant flats are far better choices. Many people bring a pair of comfortable flats to change into later in the evening.
• Train length - a long train looks beautiful but becomes impractical when you're navigating crowded food stalls and dodgem queues. If your dress has a long train, consider whether it can be bustled or pinned up.
• Pockets - if your outfit has pockets, you've won. If not, bring a small clutch or crossbody bag for your phone and portable charger.
• Layers - temperatures in Cambridge can drop to 8-10°C by 3am, even in mid-June. A pashmina, shawl, or wrap is essential. Leave it at the coat check and collect it later in the evening.

National Dress

National or cultural dress is always welcome at Cambridge May Balls, regardless of the stated dress code. Whether it's a sari, a sherwani, a kilt with full Highland dress, a hanbok, an ao dai, or any other form of traditional formal attire, it is entirely appropriate and you will not be out of place. Cambridge is an international university and May Ball committees explicitly welcome national dress as formal attire.

Budget Options

You do not need to spend a fortune to look good at a May Ball. Here are some practical options:

Suit and Tuxedo Hire

• Moss Bros - the most well-known formalwear hire chain in the UK. Black tie hire starts from around £70-100 for a full set. They have an online fitting service and deliver nationwide. White tie hire is also available.
• Slaters - a good option if you'd rather buy than hire. You can get a reasonable dinner suit from £100-150 that you'll own and can re-use.
• ASOS, Zara, or H&M - budget dinner jackets and trousers for under £100. The quality won't be as good, but they'll look fine for one night.
• Borrow from a friend - if you have a friend of similar build who owns a dinner suit, this is the cheapest option of all.

Dress Rental

• HURR - an online dress rental platform with a wide selection of designer gowns and formal dresses. Rentals start from around £30-50 for a four-day hire.
• By Rotation - peer-to-peer fashion rental where you can find designer pieces at a fraction of the retail price.
• Vinted and Depop - secondhand formal dresses often go for a fraction of their original price. You can sell the dress afterwards to recoup some of the cost.
• Charity shops in Cambridge - the charity shops along Burleigh Street and Mill Road occasionally have formal dresses, especially in May Week season when people donate after graduating.

Cambridge-Specific Options

• College swaps and social media - many colleges have swap shops or Facebook groups where students sell or lend formalwear. Check your JCR/MCR social media pages.
• The Cambridge Formal Exchange - various student-run groups on Facebook facilitate buying, selling, and lending formal clothing around May Week.

What NOT to Wear

A few things to avoid:

• A lounge suit (ordinary business suit) - a dark suit without a dinner jacket is technically below the dress code at a black tie event. In practice, some balls will let you in, but you'll feel underdressed all night.
• Trainers or casual shoes - even if your outfit is otherwise formal, trainers will get you stopped at the gate.
• Novelty formalwear - coloured dinner jackets, comedy bow ties, or themed outfits. Unless the ball specifically has a theme that calls for it, stick to the traditional dress code.
• Brand new shoes you haven't broken in - nine hours in stiff new shoes will leave you with blisters. Wear them around the house a few times first.
• Anything you can't move in - you'll be dancing, eating, queuing, and possibly riding dodgems. Your outfit needs to let you do all of that.

The Bottom Line

A May Ball is one of the few occasions where you get to dress up properly. Embrace it. But prioritise comfort and practicality alongside style - the best-dressed person at the ball is the one who's still dancing at 5am, not the one who went home at midnight because their shoes hurt.

If you're on a budget, hire rather than buy, and invest the saved money in comfortable shoes and a warm layer. Nobody will remember what brand your dinner jacket was. They will remember whether you had a good time.
