How to Buy Your First Suit: A Guide for Prom and Big Firsts

Buying is almost always the better decision. Rentals typically run 150 to 300 dollars and go back after one night, while a purchased navy or charcoal suit keeps earning its cost at graduation, weddings and job interviews.

Yes, and for most proms a suit is the better choice. It works across nearly every venue, gives you more room with color and style, and stays in your wardrobe after the night is over.

A tuxedo is defined by its satin details, including satin lapels, a satin stripe down the trouser leg and a formal dress shirt. Save it for black-tie or grand ballroom proms, while a suit suits most other venues.

Navy is the most reliable choice. It photographs well in every kind of light, flatters virtually every skin tone and will keep serving you long after prom, while charcoal is a strong formal alternative.

Make one strong choice and keep everything else clean. A deep jewel tone like burgundy or emerald works beautifully when paired with a white shirt and simple accessories that do not compete with it.

Close to the body without being tight. The shoulder seams should sit at the edge of your shoulders, the sleeves should show about a quarter inch of shirt cuff, and the trousers should break cleanly over the shoe.

Black Oxford or Derby shoes for traditional venues, or dark brown Derbies or a refined loafer for more relaxed settings. Skip athletic sneakers, since your shoes should match the formality of the suit.

Aim for complementary rather than identical. Choose a tie or pocket square in a tone that references your date's color instead of matching the whole suit to it, which tends to look like a costume.

For made-to-measure, book your measurement appointment about six to eight weeks before prom. Younger bodies are often still changing, so for off-the-rack, buy closer to the date and have alterations done in the final weeks.

Fit first, then a versatile color and quality fabric. A well-fitted navy or charcoal suit chosen for prom will carry you through graduation, friends' weddings and your first job interviews.
