Dress code rules are the basis for all these yearly memorable and special events such as weddings, but because of your significant role as a Groomsman, you should look into whether the wedding is formal and at what time of the year it falls on. Not taking note of this really could result in a faux-pas that will haunt you forever! Needless to say these suggestions apply to all sorts of wedding types.

Follow the book 

Some people will often say only wear a tuxedo if you’re the groom since it is his uniform for the day. He may choose not to wear one but that is his prerogative - he is the main man of the day after all... 

However, many Groomsmen will go for the matching Tuxedos option and it is becoming more common to see this at modern day weddings. This is because it is said that the Groom and Groomsmen should be at the same level of uniform formality and a Tuxedo among suits may look a little misplaced. 

So the the full matching tuxedo option is perfectly fine, and the groom can be set apart by some simple small stylish details and accessories.

Going Formal 

If the day warrants top hat and tails, then go along with it and the devil is truly in the detail, as they can be a little pricey, so do check out The WeddingSite Budget Tracker or the Conde Nast Brides show in London for stylish inspiration and research. 

It is also worth noting that traditionally tuxedos are seen as evening attired only, so not before 6pm in the evening. But hey, that's just strict tradition! 

A good strong suit is also quite acceptable too. Preferably, it should be more on the formal suit side of the spectrum, like a navy double-breasted or three-piece with French cuffs and classic black oxford shoes (well shined).

Daytime and informal 

Winter - whether you are the IT geek of the group with that trademark "smart boy hair" and glasses or the suave "clean-cut" business type, the groom and your friends will accept anything that will make you comfortable so no need to do anything too drastic. 

But it’s worth mentioning that wearing a heavier suit fabric such as heritage tweed or wool is appropriate for the season, preferably dark or a navy blue with perhaps flannel grey colour trousers. Don’t bother with a tie and perhaps you may choose a roll neck if you’re in a Steve McQueen mood. 

Summer - wear light fabrics such as linen, it wears well, will keep you cool and the slight creases will add a bit of Sprezzatura to your look. Or if you prefer a dark navy blue colour, combine it with white or cream and don’t forget to wear a classic Fedora hat in either ivory or natural to properly play the part of a perfect Beach Wedding day to remember.
