Got your prom suit sorted? Good. Now for a lesson in accessorising. Note-taking is optional but a well-rounded prom look is essential.

The list of bow tie wearers is a long one, from old Hollywood movie stars to current red carpet regulars and, of course, just about every James Bond ever. In other words: it’s shorthand for suave. Usually worn with a tuxedo, as shown here, but equally as stylish with a three-piece suit. Go for a pre-tied bow tie for ease or, if you’re up for the challenge, here’s how to tie a bow tie from scratch.

Tucking a pocket square into your top pocket is one of the easiest ways to take your look from so-so to sharp. Choose one that complements but contrasts with the colour of your suit. Extra marks for pattern-clashing with your shirt. And while we’re on the subject, there are loads of ways to fold your pocket square, but these two are a good place to start.

Kim and Kanye. Chris and Kem. Suit and tie. There are some pairs that are just meant to be. If you’re wearing a tie to prom there are few things you need to remember. Your tie should be a similar width to your lapels (so a skinny fit suit gets a skinny tie, a mid-width lapel needs a tie that’s little wider). As for colour, you can go one of two routes. For a pulled together look, choose one that’s a similar shade to your outfit. For a bolder look, pick one that’s a contrasting colour, as shown above. Either way, make sure your tie is always darker than your shirt.

We’ll shout about the importance of accessories any time, any place, but sometimes simple really is best. See our boy above – he’s already got a sharp suit in this season’s pastel blue and a graphic print shirt. Anything extra would just be a distraction from a strong look. The lesson here? If you think it looks too much, it probably is.
