If there is a prom theme, this might also have an impact on his outfit choice. For example, an Old Hollywood theme might call for an outfit inspired by a classic actor. Make sure to tell your date if there is any theme chosen so he can keep this in mind and use it to get creative with his look. 

Most guys attending prom have 2 options - to rent or buy a suit. Renting is a good option if he only needs a suit for a one-off event. However, having a great neutral colored suit is essential for most men and can be seen as something to invest in for future events and interviews, etc. Even if your date decides to rent a suit, he will probably need to purchase the rest of the outfit, including a shirt, tie, and formal shoes. He may ask for your help to choose these or simply do his best to match them to your dress himself.

Trying to decide what color your date should wear can be a little tricky, especially if your prom dress has a few different colors. It's true that certain suit colors match better to certain dress colors. Navy suits match well with blush, burgundy, green and metallic dresses. Silver/grey suits go well with lighter pastel tone and very bright designs and of course, a black tuxedo goes with pretty much every color. If in doubt, ask him to wear a simple black suit/tux. 

It's a great idea to pick your dress first if possible, so he can pick the right color for his suit. There's just so much choice of gowns for prom. He can take along an image of the dress as a guide when he goes to buy or rent his outfit. The rest of his outfit should also be considered. He'll need a neutral shirt that doesn't clash with your dress colors (white always works) and then a tie to complete the outfit. 

A tie doesn't have to match, but it can look great if it does! Many prom couples use the tie as a way to match both outfits together, picking a tie color that is close in tone to the dress. If this isn't possible, you could also pick a metallic tie that suits the embellishment of your dress. This is subtle but really looks pretty. Alternatively, ask your date to pick a simple black or white tie, and then wear black and white shoes and a clutch. 

While your chosen corsage and boutonniere should match your dress and suit, there should also be some contrast. For example, a black suit looks best with a white boutonniere. White is a good base tone, but the florist can also add a flower in a lighter pastel tone that's a similar shade to your dress (if your dress is dark, or vice versa). This makes your corsage more personalized and coordinating. If you need help, just bring an image of your dress to the florist when you go to make an order. 

Not everyone takes a date to the prom, some go with their besties or friend group instead, which is a great way to enjoy the night! If you choose this option, you might want to coordinate two or more prom dresses, if you want to tie your outfits together and look matching for photos. You don't have to do this, but it can work out beautifully and makes it clear that you're going as a group. Here are a few ways to match your friends' prom dresses with your own.
