There's nothing worse than totally metamorphosing Kafkaesque-like into a different creature on your wedding day. Even though the temptation for many women (and a handful of men) to live their very own fairy tale seems insurmountable, try to resist it. Apart from all the other details that should correspond to the style of wedding you and your beloved choose, your respective fragrances should reflect an extension of your personality, exalted to its best, with just that extra little touch for marking the day as more special than any other. In perfume terms, that means your signature scent might be a little too predictable, even if perfect for you, necessitating to go the extra mile. A subtle twist might be just the thing to create an indelible mark on your beloved's memory and that special aura that will put you in the accompanying festive mood.
Another important, perhaps even more important, consideration is how your fragrance will mingle with the weather, the surroundings, the conditions in which you will be subjected to: Don't try to beat a Florida summer wedding with humidity tilting at 98% by wearing your beloved heavy oriental that was perfect back in wintertime Chicago. Don't subject your guests to gusts of soured juice coming off your bridal dress. Similarly, an over-ornate baroque composition might seem a little pretentious on a beach ceremony where you're appearing barefoot, and a meaningful exclusive niche might go amiss on a groom with no tie and no jacket. There's a reason why the Greek word ωραίος (synonym for "beautiful", but even more exalted to include intelligence and smarts in the mix) literally means "in good time" : synchronizing with your surroundings is considered the ne plus ultra of the elegant person.
This is also not the time nor the place to experiment with weird scents, hoping to pass off as more sophisticated than you are. Weddings are by their own nature a bit of a conservative occasion, a celebration of the ritualistic triumph over unconventionality, so there's only so much you can get away with. Perhaps another consideration for the bride especially is what flowers will the bouquet contain: you wouldn't want to drown out the delicate scent of roses with an overpowering resinous perfume as you wouldn't want to pair daisies with a bitter-tinged, very elegant chypre.
Above all, apply lightly, renew if need be in the middle of the reception, or plan ahead using the technique of layering body cream in a matching scent ~if available~ for long-lasting effects and don't give it too much fret and fuss. Perfume is supposed to be enjoyable, not stressful!
So, catering to different types (because come on, admit it, that's how all wedding planners guide you, don't they) I have come up with suggestions for scents for the ladies and the gentlemen on this precious path to a new life. Naturally, feel free to add your own, sample lots of things as soon as you decide on the date, bring your beloved along for the testing and allow perfume some time to mingle with your sensibilities and your skin before making any final decision. You will (hopefully) want to remember this scent for the rest of your life.
