When we talk about wedding outfits for men, the black tie, formal, cocktail, including semi-formal, and casual wedding dress codes are those discussed below, since black tie is a prominent category of the wedding event.
White-tie is one of the more complex dress codes, which is why if you are invited to a White-Tie Wedding, it is essential that you do this correctly. White-tie wedding dress is the most formal of the dress codes, and that means tassels on your jacket, maybe an eye-patch (kidding…sorta).
White tie is also the place to get a tailsy (a jacket with the back coming up to about knee height), but be aware it is a rare requirement for American festivities. You can dress this up, however: Try a satin black necktie or black-and-white pattern bowtie.
The most conservative choice is a black tie, black vest, or cummerbund with suspenders, but a white dinner jacket with black tuxedo pants is also acceptable in summer months. When wearing a well-fitting black suit, the look can be just as striking as the tuxedo, yet still be appropriate to the occasion.
If you can be comfortable and confident wearing a base suit that fits the occasion and the dress code, then by all means, do so. You can probably even get away with wearing a conservative black suit instead of a tux. In this case, a black suit and tie would be acceptable wedding outfits for men, but do go for a tux if you are able. Black tie spring wedding dress for men means that you are going to want to have a sharp tuxedo, either black or midnight blue.
In black-tie, the bow tie is still your best neckwear option–though nowadays, you may occasionally get away with just a plain necktie–and the shoes must remain black. Wear appropriate tie, and, once again, black is the primary color for grooms, black bowties with the tuxedo, or a knot tie with the black on the suit, are appropriate styles for their wedding day.
If you see the words black tie required, black tie requested, or black tie welcomed in the invitation, then you are going to want to dress up. At a black tie wedding, the male guests will be expected to wear dinner jackets that have thin satin or silk lapels, no back vents, or pleats. Formal attire may mean the traditional matched dinner jacket, but this does not need to be black (navy, hunter green, and burgundy are all trendy options), or trousers and the formal dinner jacket, which does not need to be matched.
For example, a wedding at the church would typically require a smart black or gray lounge suit, but for an outdoor wedding at the beach or a park, a linen suit in a lighter pastel hue may work better (and feel more comfortable). At a casual wedding, you have a lot of freedom as far as what colours you can wear, so do not be afraid to liven things up a bit with some pastel shades.
You can stick with basics if you like, but a smart casual wedding is also a welcome opportunity to go for some brightly-coloured suiting, along with some more visible patterns. A simple dress shirt will do the trick, but something a bit more unusual is a refreshing way to shake up the standard wedding outfit.
Hopefully, your wedding invitations will state whether a dress is beach casual or beach formal, but a good rule for beach wedding outfits is to wear something that you would wear to a nice restaurant on a sunny afternoon. If the invitation specifies a casual dress code, you may want to skip a linen suit and simply wear a t-shirt and pants instead.
Unless you are having a theme wedding, or this is the elegant Classic Coat Suit Style wedding, choosing a wedding suit is pretty much the ultimate casual look for guests. You can dress it up a bit by adding white or black bowtie, lapel pins, or wedding shoe spikes, but there is not much scope for personality.
